- NASA/GSFC HEASARC
- Description:
- The Hipparcos and Tycho Catalogues are the primary products of the European Space Agency's astrometric mission, Hipparcos. The satellite, which operated for four years, returned high quality scientific data from November 1989 to March 1993. Each of the catalogues contains a large quantity of very high quality astrometric and photometric data. In addition there are associated annexes featuring variability and double/multiple star data, and solar system astrometric and photometric measurements. In the case of the Hipparcos Catalogue, the principal parts are provided in both printed and machine-readable form (on CDROM). In the case of the Tycho Catalogue, results are provided in machine-readable form only (on CDROM). Although in general only the final reduced and calibrated astrometric and photometric data are provided, some auxiliary files containing results from intermediate stages of the data processing, of relevance for the more-specialised user, have also been retained for publication. (Some, but not all, data files are available from the Centre de Donnees astronomiques de Strasbourg.) The global data analysis tasks, proceeding from nearly 1000 Gbit of raw satellite data to the final catalogues, was a lengthy and complex process, and was undertaken by the NDAC and FAST Consortia, together responsible for the production of the Hipparcos Catalogue, and the Tycho Consortium, responsible for the production of the Tycho Catalogue. A fourth scientific consortium, the INCA Consortium, was responsible for the construction of the Hipparcos observing programme, compiling the best-available data for the selected stars before launch into the Hipparcos Input Catalogue. The production of the Hipparcos and Tycho Catalogues marks the formal end of the involvement in the mission by the European Space Agency and the four scientific consortia. For much more information about this catalog, such as fuller descriptions of the parameters, the user is urged to check the Hipparcos and Tycho Catalogs website at <a href="https://www.cosmos.esa.int/web/hipparcos/catalogues">https://www.cosmos.esa.int/web/hipparcos/catalogues</a>. This database table was created by the HEASARC in April 2000 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/I/239">CDS Catalog I/239</a> file hip_main.dat.gz, the Hipparcos Main Catalog. It was updated in October 2002 to fix some entries which were missing coordinates. This is a service provided by NASA HEASARC .

- Hipparcos New Astrometric Catalog
- Short Name:
- HIPNEWCAT
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than Hipparcos magnitude H_p = 8 to be better, by up to a factor 4, than in the original catalog. The new Hipparcos astrometric catalog has been checked for the quality of the data and the consistency of the formal errors as well as the possible presence of error correlations. The differences with the earlier publication of the Hipparcos Catalog are explained in the reference paper. The internal errors are followed through the reduction process, and the external errors are investigated on the basis of a comparison with radio observations of a small selection of stars, and the distribution of negative parallaxes. Error correlation levels are investigated and the reduction by more than a factor 10 as obtained in the new catalog is explained. The formal errors on the parallaxes for the new catalog are confirmed. The presence of a small amount of additional noise, though unlikely, cannot be ruled out. The new reduction of the Hipparcos astrometric data provides an improvement by a factor 2.2 in the total weight compared to the Hipparcos catalog published in 1997, and, according to the author, provides much improved data for a wide range of studies on stellar luminosities and local galactic kinematics. Note that this catalog version is slightly different from the one published in the book, as an error that sometimes affected the goodness of fit value for the solution was corrected. The first version of these data archived at the CDS (between June and 15 September 2008) also contained errors which were corrected after this date. This table was created by the HEASARC in August 2009 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/I/311">CDS Catalog I/311</a> file hip2.dat, "the Astrometric Catalogue".

- Large Magellanic Cloud Extended Objects Catalog
- Short Name:
- LMCEXTOBJ
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- A survey of extended objects in the Large Magellanic Cloud (LMC) was carried out on the ESO/SERC R and J Sky Survey Atlases, checking entries in previous catalogs and searching for new objects. The census provided 6659 objects including star clusters, emission-free associations, and objects related to emission nebulae. Each of these classes contains three subclasses with intermediate properties, which are used to infer total populations. The survey includes cross-identifications among catalogs, and includes 3246 new objects (~49% of the unified catalog). The authors have provided accurate positions, classification, and homogeneous measurements of sizes and position angles, as well as information on cluster pairs and hierarchical relation for superimposed objects. This unification and enlargement of catalogs is important for future searches of fainter and smaller new objects. The present catalog together with its previous counterpart for the SMC and the inter-Cloud region provide a total population of 7847 extended objects in the Magellanic System. The angular distribution of the ensemble reveals important clues on the interaction between the LMC and SMC. This table was created by the HEASARC in March 2007 based on the CDS table J/AJ/117/238, file table2.dat and contains the 6659 extended objects found in this LMC survey.

- Lepine and Shara Northern Stars Proper Motion (LSPM-North) Catalog
- Short Name:
- LSPMNORTH
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The LSPM catalog is a comprehensive list of 61,977 stars north of the J2000 celestial equator that have proper motions larger than 0.15" yr<sup>-1</sup> (local-background-stars frame). The catalog has been generated primarily as a result of the authors' systematic search for high-proper-motion stars in the Digitized Sky Surveys using their SUPERBLINK software (note that this catalog is consequently also sometimes referred to as the SUPERBLINK Catalog). At brighter magnitudes, the catalog incorporates stars and data from the Tycho-2 Catalog and also, to a lesser extent, from the All-Sky Compiled Catalogue of 2.5 million stars (ASCC-2.5: Kharchenko 2001). The LSPM catalog considerably expands over the old Luyten (Luyten Half-Second (LHS) and New Luyten Two-Tenths (NLTT) catalogs, superseding them for northern declinations. Positions are given with an accuracy of <~ 100 milliarcseconds (mas) at the 2000.0 epoch, and absolute proper motions are given with an accuracy of ~ 8 mas/yr. Corrections to the local-background-stars proper motions have been calculated, and absolute proper motions in the extragalactic frame are given. Whenever available, the authors also give optical B<sub>T</sub> and V<sub>T</sub> magnitudes (from Tycho-2, ASCC-2.5), photographic B<sub>J</sub>, R<sub>F</sub>, and I<sub>N</sub> magnitudes (from the USNO-B1 catalog), and infrared J, H, and K<sub>s</sub> magnitudes (from 2MASS). An estimated V magnitude and V-J color is also provided for nearly all catalog entries, which is useful for initial classification of the stars. The catalog is estimated to be over 99% complete at high Galactic latitudes (|b| > 15 degrees) and over 90% complete at low Galactic latitudes (|b| < 15 degrees), down to a magnitude of V = 19.0, and has a limiting magnitude V = 21.0. All the northern stars listed in the LHS and NLTT catalogs have been re-identified, and their positions, proper motions, and magnitudes reevaluated. The catalog also lists a large number of completely new objects, which promise to expand very significantly the census of red dwarfs, sub-dwarfs, and white dwarfs in the vicinity of the Sun. All of Luyten's NLTT stars north of the J2000 celestial equator that do NOT appear in the LSPM Catalog are listed in Table 3 of the published paper, together with the explanations as to why they were not included in the LSPM Catalog. This table was created by the HEASARC in June 2013 based on an electronic version of Table 1 from the reference paper which was obtained from the CDS web site (their catalog I/298).

- LMC Clusters Catalog
- Short Name:
- LMC/Cluster
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- A new catalogue of clusters in the Large Magellanic Cloud has been constructed from searches of the IIIa-J component of the ESO/SERC Southern Sky Atlas. The catalogue contains coordinate and diameter measurements of 1762 clusters in a 25 deg x 25 deg area of sky centered on the LMC, but excluding the very crowded 3.5 square deg region around the Bar. The distribution of these clusters appears as two superimposed elliptical systems. The higher density inner system extends over about 8 deg; the lower density outer system can be represented by 13 deg X 10 deg disc inclined at 42 deg to the line of sight. There are suggestions of two weak "arms" in the latter. This is a service provided by NASA HEASARC .

- Low-Mass X-Ray Binary Catalog (4th Edition, 2007)
- Short Name:
- LMXB
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is the Fourth Edition of the Catalog of Low-mass X-ray Binaries (LMXBs) in the Galaxy and the Magellanic Clouds. The catalog has a companion catalog of high-mass X-ray binaries (HMXBs) which is called HMXBCAT in the HEASARC database system). The catalog contains source name(s), coordinates, X-ray flux, system parameters, and stellar parameters of the components and other characteristic properties of 187 low-mass X-ray binaries, together with references to a comprehensive selection of the relevant literature. The aim of this catalog is to provide some basic information on the X-ray sources and their counterparts in other wavelength ranges (gamma-rays, UV, optical, IR, and radio). Some sources, however, are only tentatively identified as low-mass X-ray binaries on the basis of their X-ray properties being similar to the known low-mass X-ray binaries. Further identification in other wavelength bands is needed to finally determine the nature of these sources. In cases where there is some doubt about the low-mass nature of the X-ray binary, this is mentioned. Literature published before 1 October 2006 has, as far as possible, been taken into account. This online catalog was created by the HEASARC in September 2007 based on machine-readable tables obtained from the ADC/CDS data centers (their catalog J/A+A/469/807, tables lmxb.dat and lmxbnote.dat).

- Lynga Open Clusters Catalog
- Short Name:
- LyngaOpenCl
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is a catalog of open cluster data, as compiled by Gosta Lynga, Lund Observatory. The aim of this catalog is to give salient data for all known open star clusters in our galaxy. As far as possible only published data values have been quoted; for some of the parameters, these values have been slected from references which can be obtained from the HEASARC. This data in part results from the merging of the data resulting from a joint project between K. Janes, C. Duke and Lynga, herein refered to as JDL data. The aim of that project was to discuss properties of the open cluster system by using existing data and by taking their accuracy into proper regard. Thus the data were assessed, mostly by Janes, weight assigned and weighted mean values derived of reddenings, turn-off colors and distances. This is a service provided by NASA HEASARC .

- Magellanic Catalog of Stars
- Short Name:
- MACS
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Magellanic Catalogue of Stars (MACS) is based on scans of ESO Schmidt plates and contains about 244,000 stars covering large areas around the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC). The positions refer to the FK5 system via the PPM Catalog. A comparison of positions from different plates shows internal errors at a level of 0.15 to o.23 arcseconds; the positional accuracy is estimated to be better than 0.5 arcseconds for 99% of the stars. The limiting blue magnitude of the MACS is less than 16.5 magnitudes, but the catalog is not complete to this level, as only those stars are included which are undisturbed by close neighbors as verified by visual (interactive) screening (in order to obtain a clean astrometric reference). This database table was created at the HEASARC in June 1998 based on the ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/I/221">CDS Catalog I/221</a>. This is a service provided by NASA HEASARC .

- Magellanic Clouds High-Mass X-Ray Binaries Catalog
- Short Name:
- MCHMXRB
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains a catalog of high-mass X-ray binaries (HMXBs) in the Small and Large Magellanic Clouds (SMC and LMC). The catalog lists source name(s), coordinates, apparent magnitudes, orbital parameters, and X-ray luminosities for 128 HMXBs, together with the stellar parameters of the components, other characteristic properties and a comprehensive selection of the relevant literature. The aim of this catalog is to provide easy access to the basic information on the X-ray sources and their counterparts in other wavelength ranges (UV, optical, IR, radio). Most of the sources have been identified as Be/X-ray binaries. Some sources, however, are only tentatively identified as HMXBs on the basis of a transient character and/or a hard X-ray spectrum. Further identification in other wavelength bands is needed to finally determine the nature of these sources. In cases where there is some doubt about the high-mass nature of the X-ray binary this is mentioned. Literature published before 1 May 2005 has, as far as possible, been taken into account. Information on the numbers used to code references is available at <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/442/1135/refs.dat">CDS</a>. Individual notes on each HMXB are also available for <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/442/1135/notes1.dat">SMC systems</a> and for <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/442/1135/notes2.dat">LMC systems</a> at the same site. This Browse table contains the combination of 92 HMXBs in the SMC and 36 HMXBs in the LMC which were listed in Tables 1 and 2, respectively, of the published version of this catalog. The HEASARC has added a parameter called cloud_id which can be used to identify which Magellanic Cloud any specified HMXB belongs to (the SMC or the LMC). This database was created by the HEASARC in December 2005 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/442/1135">CDS Catalog J/A+A/442/1135</a>, table1.dat and table2.dat.

- McCook-Sion White Dwarf Catalog (Web Version)
- Short Name:
- WDw/MS
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Web Version of the McCook-Sion White Dwarf Catalog contains in excess of 500 more entries than the previous published version, the 4th Edition (1999) of the Villanova White Dwarf Catalog. It is a catalog of white dwarfs which have been identified spectroscopically. For each degenerate star, the following data entries with references are provided: (1) catalog coordinate designation or WD number, (2) the right ascension and declination, (3) the spectral type based upon the new system, (4) a catalog symbol denoting binary membership, (5) proper motion and position angle, (6) broad-band UBV Photometry, V, B-V, U-B, (7) multichannel spectrophotometry, V(MC), g-r, (8) Stromgren narrow-band photometry y, b-y, u-b, (9) an absolute visual magnitude based upon the best available color-magnitude calibration or trigonometric parallax, (10) the observed radial velocity uncorrected for gravitational redshift or solar motion, and (11) the trigonometric parallax, with mean error, when available. Note that finding charts for many of the white dwarfs present in this catalog can be found at the following URLs: <pre> <a href="http://procyon.lpl.arizona.edu/WD/charts/">http://procyon.lpl.arizona.edu/WD/charts/</a> <a href="http://deneb.astro.warwick.ac.uk/phsaap/wdcharts/">http://deneb.astro.warwick.ac.uk/phsaap/wdcharts/</a> </pre> The second URL contains the finding charts from T.R. Marsh. This is list with about 600 charts. The University of Arizona charts currently have about 2000 charts, but that list is a work in progress with the intent of eventually having all charts available. As discussed in more detail in the HEASARC_Implementation section, this HEASARC representation of the White Dwarf Catalog contains only a subset of the data presented in either the printed version or the version available at the Villanova website, but is intended to be suitable for cross-identification purposes with other catalogs, e.g., of X-ray sources. The original sources for this catalog should always be consulted for the full set of information that is available for these white dwarfs. This database table is based on the Web version of the Villanova White Dwarf Catalog. It was initially created by the HEASARC in May 2003. It is based on the files WD00-07.txt, WD08-15.txt, WD16-23.txt, and WDNewStars.txt obtained from <pre> <a href="ftp://astronomy.villanova.edu/mccook/Current%20Web%20Version%20of%20WD%20Catalog/">ftp://astronomy.villanova.edu/mccook/Current%20Web%20Version%20of%20WD%20Catalog/</a> </pre> It is automatically updated periodically whenever the catalog's authors update these files.
