- INTEGRAL Public Data Results Catalog
- Short Name:
- INTEGRAL
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The INTEGRAL Public Data Results Catalog is based on publicly available data from the two main instruments (IBIS and SPI) on board INTEGRAL (see Winkler et al. 2003, A&A, 411, L1 for a description of the INTEGRAL spacecraft and instrument packages). INTEGRAL began collecting data in October 2002. This catalog will be regularly updated as data become public (~14 months after they are obtained). This catalog is a collaborative effort between the INTEGRAL Science Data Center (ISDC) in Switzerland and the NASA Goddard Space Flight Center (GSFC) INTEGRAL Guest Observer Facility (GOF). The results presented here are a result of a semi-automated analysis and they should be considered as approximate: they are intended to serve as a guideline to those interested in pursuing more detailed follow-up analyses. The data from the imager ISGRI (Lebrun et al. 2003, A&A, 411, L141) have been analyzed at the INTEGRAL Science Data Centre (ISDC), while the SPI (Vedrenne et al. 2003, A&A, 411, L63) data analysis was performed at GSFC as a service of the INTEGRAL GOF. Note: For cases where two or more proposals have been amalgamated (entries with pi_lname = 'Amalgamated') for a given observation, the same observation is listed for each of the amalgamated proposal numbers. This database table was first created in September 2004. It is based on the online web page maintained by the INTEGRAL GOF at the URL <a href="http://heasarc.gsfc.nasa.gov/docs/integral/obslist.html">http://heasarc.gsfc.nasa.gov/docs/integral/obslist.html</a> and was updated on a weekly basis whenever that web page was updated. Automatic updates were discontinued in June 2019. Duplicate entries were removed in June 2019, also. This is a service provided by NASA HEASARC .

- Title:
- INTEGRAL Public Pointed Science Window Data
- Short Name:
- INTSCWPUB
- Date:
- 25 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- Because of the pointing-slew-pointing dithering-nature of INTEGRAL operations, each observation of a celestial target is actually comprised of numerous individual S/C pointings and slews. In addition, there are periods within a given sequence where scheduled observations occur, i.e., engineering windows, yet the instruments still acquire data. The INTEGRAL Science Data Center (ISDC) generalizes all of these data acquisition periods into so-called `Science Windows.' A Science Window (ScW) is a continuous time interval during which all data acquired by the INTEGRAL instruments result from a specific S/C attitude orientation state. Pointing (fixed orientation), Slew (changing orientation), and Engineering (undefined orientation) windows are all special cases of a Science Window. The key is that the same attitude information may be associated with all acquired data of a given Science Window. Note that it is possible to divide a time interval that qualifies as a Science Window under this definition into several smaller Science Windows using arbitrary criteria. The INTEGRAL Public Pointed Science Window Data Catalog is a subset of the INTEGRAL Science Window Data Catalog. It only includes pointed science windows that have non-private proprietary status and at least one instrument's "good" exposure time greater than zero. This database table was first created at the HEASARC in October 2004. It is a slightly modified mirror of the online database maintained by the ISDC at the URL <a href="http://isdc.unige.ch/index.cgi?Data+browse">http://isdc.unige.ch/index.cgi?Data+browse</a> <p> The HEASARC version of this table is updated automatically within a day of the ISDC updating their database table.

- INTEGRAL Reference Catalog
- Short Name:
- INT/RefCat
- Date:
- 25 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The original version of the INTEGRAL Reference Catalog as published in 2003 classified previously known bright X-ray and gamma-ray sources before the launch of INTEGRAL. These sources are, or have been at least once, brighter than ~1 milliCrab above 3 keV energy, and are expected to be detected by INTEGRAL. This catalog was used in the INTEGRAL Quick Look Analysis (QLA) to discover new sources or significantly variable sources. The authors compiled several published X-ray and gamma-ray catalogs, and surveyed recent publications for new sources. Consequently, there were 1121 sources in the original INTEGRAL Reference Catalog. In addition to the source positions, an approximate spectral model and expected flux were given for each source, and the expected INTEGRAL counting rates based on these parameters was derived. Assuming the default instrument performances and at least ~10<sup>5</sup> seconds exposure time for any part of the sky, it is expected that INTEGRAL will detect at least ~700 sources below 10 keV and ~400 sources above 20 keV over the mission life. After the launch of INTEGRAL, a version of this catalog was placed on the ISDC website at <a href="http://www.isdc.unige.ch/integral/science/catalogue">http://www.isdc.unige.ch/integral/science/catalogue</a> and has been updated periodically since then by adding, for example, new sources discovered by INTEGRAL itself (indicated by the IGR prefix in the name). This HEASARC table is based on the web version at the ISDC, and will be updated within a few days of whenever the latter is updated. This database table is updated automatically in the HEASARC database system within one week of any changes to the online web page maintained by the INTEGRAL Science Data Center at the URL <a href="http://www.isdc.unige.ch/integral/catalog/latest/catalog.html">http://www.isdc.unige.ch/integral/catalog/latest/catalog.html</a> This is a service provided by NASA HEASARC .

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains the IRAM 30-m single-dish telescope observation log. The Institut de Radio Astronomie Millimetrique (IRAM) was founded in 1979 and is operated as a French-German-Spanish collaboration. Its partner institutes are the CNRS (Centre National de la Recherche Scientifique, France), the MPG (Max Planck Gesellschaft, Germany), and the IGN (Instituto Geografico Nacional, Spain). The principal activity of IRAM is the study of cold matter (molecular gas and dust) in the solar system, in our Galaxy, and out to cosmological distances, in order to determine its composition, density, mass, temperature, and kinematics. IRAM operates two observatories at millimeter wavelengths which are open to the international astronomical community: the 30-m single-dish telescope on Pico Veleta (2850 m), Spain, and the six-antenna interferometer on the Plateau de Bure (2550 m) in France. Both sites are at high altitude to reduce the absorption by water vapor. The observatories are supported by the IRAM offices and laboratories in Granada and Grenoble. The observation log included here concerns the 30-m single-dish telescope, and summarizes the observations made there since September 30, 2009. The observation log for the the six-antenna interferometer on the Plateau de Bure in France is also available as the HEASARC database table <a href="/W3Browse/ground-based/irampdblog.html">IRAMPDBLOG</a>, and the observation log for NOEMA (the NOrthern Extended Millimeter Array), the successor to the Plateau de Bure observatory, is available as the HEASARC database table <a href="/W3Browse/ground-based/iramnoelog.html">IRAMNOELOG</a>. For more information on IRAM, see <a href="http://www.iram-institute.org/">the IRAM home page</a>. This table was originally ingested by the HEASARC in January 2011. It is based on the CDS table B/iram/, files 30m.dat and 30m_pi.dat. It was last updated in September 2020, based on an updated version of these tables which were also obtained from the CDS.

The observation log included here concerns NOEMA, the NOrthern Extended Millimeter Array, and summarizes the observations made there. NOEMA is the successor to the Plateau de Bure observatory. During its history, the observatory at the Plateau de Bure underwent several track extensions, received additional antennas (all of 15-m diameter and of similar construction to the first ones) and technical upgrades. From a three-antenna interferometer with a maximum baseline of 288 meters in 1988, it has evolved to a eight-antenna array with baselines up to 760 meters in 2016. With the inauguration of the seventh antenna in September, 2014, the observatory started its transformation into NOEMA. More information about NOEMA is <a href="http://www.iram.fr/IRAMFR/GILDAS/doc/html/noema-intro-html/noema-intro.html">available at the IRAM web site</a>. The observation log for the 30-m telescope is available as the HEASARC database table <a href="/W3Browse/ground-based/iram30mlog.html">IRAM30MLOG</a>, and the observation log for the Plateau de Bure Interferometer is available as the HEASARC database table <a href="/W3Browse/ground-based/irampdblog.html">IRAMPDBLOG</a>.

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table contains results from Chandra ACIS-I and Karl G. Jansky Very Large Array 6-cm continuum observations of the IRAS 20126+4104 massive star-forming region. The authors detect 150 X-ray sources within the 17' x 17' ACIS-I field, and a total of 13 radio sources within the 9.2' primary JVLA beam at 4.9 GHz. Among these observations are the first 6-cm detections of the central sources reported by Hofner et al. (2007, A&A, 465, 197), namely, I20N1, I20S, and I20var. A new variable radio source is also reported in Section 3.2 of the reference paper, [MHA2015] VLA G78.1907+3.364. Searching the 2MASS archive, the authors identified 88 near-infrared (NIR) counterparts to the X-ray sources. Only four of the X-ray sources had 6-cm counterparts. Based on an NIR color-color analysis and on the Besancon simulation of Galactic stellar populations, the authors estimate that approximately 80 X-ray sources are associated with this massive star-forming region. They detect an increasing surface density of X-ray sources toward the massive protostar IRAS 20126+4104 and infer the presence of a cluster of at least 43 young stellar objects within a distance of 1.2 pc from this protostar. The authors observed the IRAS 20126+4104 region with the Chandra ACIS-I instrument on 2003 March 17 for a total exposure time of 39.35 ks. C-band (6 cm) continuum observations of the massive star-forming region IRAS 20126+4104 were conducted with the VLA operated by NRAO on 2011 August 7. These X-ray and radio data are augmented by NIR and optical archival data. For the Mid-IR wavelength regions, the authors searched the Spitzer Enhanced Imaging Products Point Source catalog. This table was created by the HEASARC in March 2016 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/219/41">CDS catalog J/ApJS/219/41</a> files table1.dat and table5.dat.

- Title:
- IRAS Faint Source Catalog, Version 2.0
- Short Name:
- IRASFSC
- Date:
- 25 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Faint Source Survey (FSS) is the definitive Infrared Astronomical Satellite (IRAS) data set for faint point sources. The FSS was produced by point-source filtering the individual detector data streams and then coadding those data streams using a trimmed-average algorithm. The resulting images, or plates, give the best estimate from the IRAS survey data of the point source flux density at every surveyed point of the sky. The Faint Source Catalog (FSC) is a compilation of the sources extracted from the FSS plates that have met reasonable reliability requirements. Averaged over the whole catalog, the FSC is at least 98.5% reliable at 12 and 25 microns, and ~94% at 60 microns. For comparison, the IRAS Point Source Catalog (PSC) is >99.997% reliable, but the sensitivity of the FSC exceeds that of the PSC by about a factor of 2.5. This increase in sensitivity results from the co-adding of the three separate hours-confirming (HCON) passes over the sky which were used for confirmation and not added together for the Point Source Catalog. The FSC also contains 99,973 infrared sources which are not in the PSC. The FSC contains data for 173,044 point sources in unconfused regions with flux densities typically above 0.2 Jy at 12, 25, and 60 microns, and above 1.0 Jy at 100 microns. The FSS plates are somewhat more sensitive but less reliable than the FSC; typically, only sources with SNR > 5 - 6 in the plates are contained in the FSC. The data products, the processing methods used to produce them, results of an analysis of these products, and cautionary notes are given in the Explanatory Supplement to the IRAS Faint Source Survey. This database table contains the IRAS Faint Source Catalog (FSC) (Version 2.0, released in September 1990) non-associations data. The associations data for the IRAS FSC is contained in the file <a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/156A/assoc.dat.gz">https://cdsarc.cds.unistra.fr/ftp/cats/II/156A/assoc.dat.gz</a> The FSC is limited in galactic latitude to the unconfused regions of sky in which the absolute value of BII is greater than or equal to 10 degrees at 12 and 25 microns and greater than or equal to 20 degrees at 60 microns. Because of the presence of the infrared "cirrus" at 100 microns, the FSC does not contain sources detected ONLY at 100 microns. Sources with a 100 micron detection were included in the catalog if they were bandmerged with high reliability detections at other spectral bands. For the faintest sources, the reliability exceeds 90% at 12 and 25 microns, and 80% at 60 microns. The HEASARC recreated this database table in August 2005, based on the CDS table, in an effort to modernize its parameter names and documentation, as well as to add Galactic coordinates.
