- INTEGRAL OMC First Catalog of Optically Variable Sources
- Short Name:
- INTOMCVS
- Date:
- 25 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Optical Monitoring Camera (OMC) on board the high-energy INTEGRAL satellite provides photometry in the Johnson V-band within a 5 by 5 degree field of view. The OMC is able to detect optical sources brighter than around V ~ 18, from a previously selected list of potential targets of interest. After more than nine years of observations, the OMC database contains light curves for more than 70 000 sources (with more than 50 photometric points each). The objectives of the present work have been to characterize the potential variability of the objects monitored by OMC, to identify periodic sources and to compute their periods, taking advantage of the stability and long monitoring time of the OMC. The first catalog of variable sources observed by OMC has been developed with observations from October 2002 to February 2010. To detect potential variability, the authors have performed a chi-squared test, finding 5263 variable sources, for 1337 of which the periods have been determined, out of an initial sample of 6071 objects with good photometric quality and more than 300 data points each. They have studied the potential periodicity of these sources using a method based on the phase dispersion minimization technique, optimized to handle light curves with very different shapes. For each object in the catalog, the median of the visual magnitude, the magnitude at maximum and minimum brightness in the light curve during the window of observations and the period, when found, are provided. The types of variable objects in the catalogue include eclipsing binaries, pulsating stars, rotating stars, eruptive stars, extragalactic objects, X-ray binaries, cataclysmic variables, Be stars and other objects with unknown kinds of variability. Links to charts for each object, including the DSS image around the target, the unfolded and folded light curves with the periods that the authors have derived and/or with the cataloged ones are provided in this database. This table was created by the HEASARC in January 2013 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/548/A79">CDS Catalog J/A+A/548/A79</a> file omc-var.dat.

- INTEGRAL Public Data Results Catalog
- Short Name:
- INTEGRAL
- Date:
- 25 Apr 2025
- 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 .

- 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:

- 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 .

- 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.

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.

- Short Name:

- 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.
