INTEGRAL Public Data Archive

The HEASARC mirror of the INTEGRAL Public Data Archive at the ISDC has been open since September 2004. The HEASARC archive was created to facilitate ease of data distribution for U.S.-based researchers. The HEASARC Browse facility is the preferred interface to the archive at both sites. Typical INTEGRAL data sets are large, probably of the order of several GB per observation, so please plan carefully before downloading. The download procedure as well as helpful hints for selecting data are discussed in our Data Download Cookbook.

Note: The HEASARC INTEGRAL Public Data Archive was updated to revision 3 status on October 19, 2010. For a discussion of the improvements found in this revision of the data please see the May 2010 ISDC Newsletter announcing the new data.

Archive Contents

The following tables are included in the HEASARC INTEGRAL archive and are searchable using the Browse interface.

  • INTEGRAL Science Window Data Catalog: A catalog containing a list of all INTEGRAL science windows (SCWs). This table can be searched using many observation parameters including source name, source position, good time, and observation date. This catalog is useful for retrieving low-level SCW data products (see our Data Download Cookbook).

  • INTEGRAL Public Pointed Science Window Data Catalog: A catalog containing a list of all public INTEGRAL science windows (SCWs) of type "pointing" in which the good time of at least one of the instruments is greater than 0. Thus this table does not contain slew or engineering SCWs or SCWs where no good data were acquired. Like the INTEGRAL Science Window Data Catalog, this table can also be searched using many observation parameters including source name, source position, good time, and observation date. This catalog is useful for retrieving low-level SCW data products (see our Data Download Cookbook).

  • The INTEGRAL Bright Source Catalog: A source catalog of bright sources based on all the public data. The catalog can be searched by source name, source position, source type, or observed SPI flux. ISGRI and SPI lightcurves can be retrieved for the selected sources. The measurements included in the catalog are intended to serve as a guideline to users of the INTEGRAL database, and should generally not be used directly in published materials.

  • The INTEGRAL Public Data Results Catalog: A catalog containing SPI and IBIS imaging analysis results which are given per observation or revolution. The catalog can be searched by revolution number, source name, source position, observation date, exposure time, and PI name. SPI and ISGRI imaging results can be retrieved. It is useful to specify a large search radius when searching this catalog due to the inclusion of Galactic Plane Scan (GPS) and Galactic Center Deep Exposure (GCDE) data. This catalog can also be used to retrieve low-level SCW data products (see our Data Download Cookbook).

  • The Second INTEGRAL AGN Catalog: This table contains some of the results from the analysis of INTEGRAL IBIS/ISGRI, JEM-X, and OMC data for 199 AGN (and 3 clusters of galaxies) that have been reported to be detected by INTEGRAL at energies above 20 keV. The data analysed therein allowed a significant spectral extraction on 148 objects and optical variability study of 57 AGN. Further information can be found in Beckmann, et al. 2009, A&A, 505, 417.

  • The Fourth IBIS/ISGRI Soft Gamma-Ray Survey Catalog: This table contains the Fourth IBIS/ISGRI Soft Gamma-Ray Catalog (Bird et al. 2010, ApJS, 186, 1). The scientific data set is based on more than 70 Ms of high-quality observations performed during the first 5.5 years of the Core Program and public IBIS/ISGRI observations, and covers >70% of the whole sky. This catalog comprises 723 high-energy sources detected in the energy range 17-100 keV, of which 35% are AGN, 5% are CVs, 13% are HMXBs, 13% are LMXBs, 8% are other types of objects (e.g. pulsars, SNRs, etc.), and 29% are of unknown classification.

  • The INTEGRAL Reference Catalog: The INTEGRAL Reference Source Catalogue contains all sources detected by INTEGRAL that have been brighter than 0.1 mCrab above 1 keV. It also includes (flagged separately) a number of high-energy (>10 keV) sources candidate for a detection. The latest version of the catalog is availble online at the ISDC and contains 1951 sources, of which 845 have been detected by IBIS/ISGRI and 149 by JEM-X.

  • The INTEGRAL First SPI-ACS Gamma-Ray Burst Catalog: The First INTEGRAL SPI-ACS Gamma-Ray Burst (GRB) Catalog contains the sample of gamma-ray bursts detected with the Anti-Coincidence Shield (ACS) of the SPI spectrometer on-board the INTEGRAL spacecraft for the first 26.5 months of mission operations (up to January 2005). The SPI-ACS works as a nearly omnidirectional gamma-ray burst detector above ~80 keV, but it lacks spatial and spectral information. This table lists the properties of 388 GRB candidates detected from Oct 27, 2002 to Jan 15, 2005 with the Anti-Coincidence Shield (ACS) of SPI. Further details can be in Rau et al. 2005, A&A, 438, 1175. A continuously updated on-line version of the catalog is available at: http://www.mpe.mpg.de/gamma/science/grb/1ACSburst.html

  • The INTEGRAL Observing Program Catalog: This HEASARC catalog contains the approved pointed observing programs for AO-1 through AO-8 and includes targets in both the Core Program (Guaranteed Time) pointed observations list and in the General Program (Open Time) accepted observations list. It can be search by source name, source position, exposure time, INTEGRAL proposal number, observation number, PI name, and proposal grade.

  • The INTEGRAL IBIS All-Sky Survey of Hard X-Ray Sources: This catalog contains the results of an all-sky hard X-ray survey based on almost four years of observations with the IBIS telescope onboard the INTEGRAL observatory. The dead time-corrected exposure of the survey is about 33 Ms. Approximately 12% and 80% of the sky has been covered to limiting fluxes lower than 1 and 5 mCrab, respectively. The catalog of detected sources includes 403 objects, 316 of which exceed a 5-sigma detection threshold on the time-averaged map of the sky, and the rest were detected in various subsamples of exposures. Further information can be found in Krivonos, et al. 2007, A&A, 475, 775.

  • The INTEGRAL IBIS Hard X-Ray Survey of Galactic Center Catalog: This catalog contains the IBIS/ISGRI results from the INTEGRAL deep survey of the Galactic Center using data from August 23 through September 24, 2003. This table conatins the 60 sources detected above 1.5 mCrab in the energy range 18-60 keV at the 6.5 sigma level. The catalog includes 38 LMXBs, 5 HMXBs, 2 CVs, 1 AXP, 1 SGR, and 3 extragalactic objects. Nine sources remain unidentified. Further information can be found in Revnivtsev et al. 2004, Astronomy Letters, 30, 382
