- 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:
- 18 Apr 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.

- Description:
- The Massive Young Star-forming complex Study in Infrared and X-rays (MYStIX) project requires samples of young stars that are likely members of 20 nearby Galactic massive star-forming regions. Membership is inferred from statistical classification of X-ray sources, from detection of a robust infrared excess that is best explained by circumstellar dust in a disk or infalling envelope and from published spectral types that are unlikely to be found among field stars. This table contains the MYStIX membership lists, which total 31,549 probable complex members. In their reference paper, the authors describe in detail the statistical classification of X-ray sources via a "Naive Bayes Classifier". These membership lists provide the empirical foundation for subsequent MYStIX science studies. The MYStIX project, described by Feigelson et al. (2013, ApJS, 209, 26), seeks to identify and study samples of young stars in 20 nearby (0.4 < D < 3.6kpc) Galactic massive star-forming regions (MSFRs). These samples are derived using X-ray data from the Chandra X-ray Observatory, near-infrared (NIR) photometry from the United Kingdom InfraRed Telescope (UKIRT) and from the Two Micron All Sky Survey (2MASS), mid-infrared (MIR) photometry from the Spitzer Space Telescope, and from published spectroscopically-identified massive stars. The purpose of this study is to describe the authors' efforts to minimize contaminants in the MYStIX catalogs of young stars. They refer to these latter objects as the "MYStIX Probable Complex Members" or MPCMs. This table contains the combined MPCM catalog for all 20 of the MYStIX MSFRs. This MPCM catalog is the union of three sets of probable members identified by three different established methods for identifying young stars (see Feigelson et al. 2013, ApJS, 209, 26, Fig. 3). Most of the X-ray information on the MPCMs (with the exception of the X-ray luminosities and absorbing column densities obtained using XPHOT) was produced by the ACIS Extract (AE) software package (Broos et al. 2010, ApJ, 714, 1582 and 2012, Astrophysics Source Code Library, 1203.001). The AE software and User's Guide are available at <a href="http://www.astro.psu.edu/xray/acis/acis_analysis.html">http://www.astro.psu.edu/xray/acis/acis_analysis.html</a>. X-ray quantities using the 'fb' prefix are for the full or total energy band from 0.5 - 8.0 keV, those using the 'sb' prefix are for the soft band from 0.5 - 2.0 keV, and those using the 'hb' prefix are for the hard band from 2.0 - 8.0 keV. L. K. Townsley and P. S. Broos (2013, in preparation) and Kuhn et al. (2013, ApJS, 209, 27) identify a few very bright X-ray sources in each region that suffer from a type of instrumental non-linearity known as photon pile-up (<a href="http://cxc.harvard.edu/ciao/why/pileup_intro.html">http://cxc.harvard.edu/ciao/why/pileup_intro.html</a>); X-ray properties reported for those sources are biased and should be used with caution. This table was created by the HEASARC in February 2014 based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/209/32">CDS Catalog J/ApJS/209/32</a> file mpcm.dat.

- McCook-Sion White Dwarf Catalog (Web Version)
- Short Name:
- WDw/MS
- Date:
- 18 Apr 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.

- Milky Way Globular Clusters Catalog (December 2010 Version)
- Short Name:
- GC
- Date:
- 18 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is the Catalog of Parameters for Milky Way Globular Clusters (December 2010 Version) that was compiled by William E. Harris of McMaster University. This is the first update since 2003 and the biggest single revision since the original version of the catalog published in 1996. The list now contains a total of 157 objects classified as globular clusters. Major upgrades have been made especially to the cluster coordinates, metallicities, and structural profile parameters, and the list of parameters now also includes the central velocity dispersion. This table contains basic parameters on distances, velocities, metallicities, luminosities, colors, and dynamical parameters for over 150 objects that are regarded as globular clusters in the Milky Way galaxy. Please acknowledge the use of this catalog in any published work you derive from it. The proper reference to the literature is the published paper (Harris, W.E. 1996, AJ, 112, 1487) which briefly describes the setup of the catalog. When you cite it in your text, please use "Harris 1996 (2010 edition)". The author would also greatly appreciate receiving any new information, in published or preprint form, which would help him to keep the list up to date (contact W. E. Harris at harris@physics.mcmaster.ca). A full discussion of the sources used in the creation of this catalog and of the parameters that it contains can be found in the file: <a href="http://physwww.mcmaster.ca/~harris/mwgc.ref">http://physwww.mcmaster.ca/~harris/mwgc.ref</a>. This table was originally ingested by the HEASARC circa 1995. It was last updated by the HEASARC in February 2014 based on an electronic version (dated December 2010) copied from the file <a href="http://physwww.mcmaster.ca/~harris/mwgc.dat">http://physwww.mcmaster.ca/~harris/mwgc.dat</a>.

- Description:
- Although they are the main constituents of the Galactic disk population, for half of the open clusters in the Milky Way reported in the literature nothing is known except the raw position and an approximate size. The main goal of this study is to determine a full set of uniform spatial, structural, kinematic, and astrophysical parameters for as many known open clusters as possible. On the basis of stellar data from PPMXL and 2MASS, the authors used a dedicated data-processing pipeline to determine kinematic and photometric membership probabilities for stars in a cluster region. For an input list of 3,784 targets from the literature, they confirm that 3,006 are real objects, the vast majority of them are open clusters, but associations and globular clusters are also present. For each confirmed object, the authors determined the exact position of the cluster center, the apparent size, proper motion, distance, color excess, and age. For about 1,500 clusters, these basic astrophysical parameters have been determined for the first time. For the bulk of the clusters the authors also derived the tidal radii. In addition, they estimated average radial velocities for more than 30% of the confirmed clusters. The present sample (called MWSC) reaches both the central parts of the Milky Way and its outer regions. It is almost complete up to 1.8 kpc from the Sun and also covers the neighboring spiral arms. However, for a small subset of the oldest open clusters (ages more than ~ 1 Gyr), the authors found some evidence of incompleteness within about 1 kpc from the Sun. This table contains the list of 3,006 Milky Way stellar clusters (MWSC) found in the 2MAst (2MASS with Astrometry) catalog presented in Paper II of this series (these clusters have source numbers below 4000), together with an additional 139 new open clusters (these clusters have source numbers between 5000 and 6000) found by the authors at high Galactic latitudes (|b_II_| > 18.5 degrees) which were presented in Paper III of the series, and an additional 63 new open clusters (these clusters have source numbers between 4000 and 5000) which were presented in Paper IV of the series. The target list in Paper II from which the 3,006 open clusters was contained was compiled on the basis of present-day lists of open, globular and candidate clusters. The list of new high-latitude open clusters in Paper III was obtained from a target list of 714 density enhancements found using the 2MASS Catalog. The list of new open clusters in Paper IV was obtained from an initial list of 692 compact cluster candidates which were found by the authors by conducting an almost global search of the sky (they excluded the portions of the sky with |b_II_| < 5 degrees) in the PPMXL and the UCAC4 proper-motion catalogs. For confirmed clusters, the authors determined a homogeneous set of astrophysical parameters such as membership, angular radii of the main morphological parts, mean cluster proper motions, distances, reddenings, ages, tidal parameters, and sometimes radial velocities. This table was created by the HEASARC in February 2014 based on the list of open clusters given in <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/558/A53">CDS Catalog J/A+A/558/A53</a> files catalog.dat and notes.dat. It was updated in September 2014 with 139 additional star clusters from <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/568/A51">CDS Catalog J/A+A/568/A51</a> files catalog.dat and notes.dat. It was further updated in October 2015 with 63 additional star clusters from <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/581/A39">CDS Catalog J/A+A/581/A39</a> files catalog.dat and notes.dat. Note that this table does not include the information on candidates which turned out not to be open clusters which was also contained in these catalogs. This is a service provided by NASA HEASARC .

- MIT/Amsterdam M 31 Survey
- Short Name:
- M31Stars/deep
- Date:
- 18 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The MIT/Amsterdam M 31 Survey, or the Extended Magnier et al. Catalog of Objects in the Field of M 31, is based on deep BVRI CCD photometry that was performed on a 1 square degree region of M 31. The observations were made between September 12 and September 27 1990, using the McGraw-Hill 1.3m telescope at the Michigan-Dartmouth-MIT (MDM) observatory at Kitt Peak. The catalogue has typical completeness limits of 20.7 (Bmag), 21.7 (Vmag), 20.2 (Rmag) and 20.5 (Imag), although there is a large region in the inner disk for which the completeness limits are substantially deeper: 22.3 (Bmag), 22.2 (Vmag), 22.2 (Rmag), and 20.9 (Imag). The photometric accuracy is about 2% at Vmag = 19. The final astrometric calibrations take into account the systematic error discovered in the Berkhuijsen et al. (1988, A&AS, 76, 65) catalog by Magnier et al. (1993, A&A, 272, 695). They are in the J2000 system and are eventually tied to the HST Guide Star Catalog. The final photometric calibrations are tied via the NGC 206 region to photometry taken at the Michigan-Dartmouth-MIT (MDM) 1.3m in September and October 1993. These are tied to the Landolt (1992, AJ, 104, 340) system of standard stars, and are in the Johnson-Kron-Cousins system (BVRcIc). This version of the MIT/Amsterdam M31 Survey Catalog was created at the HEASARC in March 1999 based on the CDS/ADC Catalogue II/208. The HEASARC revised this version in February 2001.

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Revised Bologna Catalogue of M 31 globular clusters and candidates (RBC, V.5, August 2012) lists all the confirmed globular clusters (GCs), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were subsequently recognized not to be genuine clusters, each entry being properly classified (GC, candidate GC, foreground star, background galaxy, HII region, etc.). The latter entries are maintained in the catalog to avoid re-discoveries of objects that may look like M 31 GCs and have been already classified as non-GCs. Please take into account the classification flag(s) when you use the RBC. Please acknowledge the use of this catalog.
