INTEGRAL Archive at HEASARC Status and Plans Steve Drake Steve Drake
INTEGRAL: Mission Status, Overview of US Program & Archive • INTEGRAL is an ESA mission with NASA participation for hard X-ray/gamma-ray (15 keV-10 MeV) imaging and spectroscopy (& soft X-ray & optical instruments) • Currently in its 4th year of operations; will be supported by ESA at least through 2010 • Spacecraft and subsystems all operating nominally • 4th GO cycle starts in August 2006 • US investigators comprise ~25% of overall GO program (supported by NASA grants) • NASA GOF mirrors ESA’s ISDC archive, and provides technical and scientific support to US astronomy community (2.5 science FTEs) • Future of NASA INTEGRAL funding to be determined by 2006 MO&DA Senior Review Steve Drake
INTEGRAL Archive: Milestones • July 2004: The ISDC INTEGRAL Public Data Archive opened with data up to revolution 66 (5-1-03). • September 2004: The US INTEGRAL Public Data Archive at the HEASARC opened. • January 2005: All public data was reprocessed into revision 2 format. - Rev 2 utilizes HEASARC-compatible event file formats • February 2005: The US INTEGRAL Public Data Archive at the HEASARC switches over to revision 2 format data. • February 2006: 1.8 TB of public INTEGRAL data available from the HEASARC (most of mission up to Jan/Feb 2005) Steve Drake
INTEGRAL Archive: Current Status • New public data is available to the community within a few days of its release from the ISDC. • The limiting factor is the low data transfer rate from the ISDC. • ~3 spacecraft orbital revolutions = 9 days of data can be transferred per day. • All public data through the latest ISDC release (03-31-06) is currently available from the HEASARC archive. Steve Drake
Accessibility • The US INTEGRAL Public Data Archive is accessible from the HEASARC via Browse or FTP. • Downloading the data as a tar file is complicated by the large size of the typical observation, 1 Rev. = 3 days of data = 7-8 GB. • The HEASARC limit for a tar file is 5 GB ==> the preferred download method is via a wget script created by Browse. • A detailed description of all the INTEGRAL catalogs available through Browse as well as a detailed cookbook describing the downloading of data : <http://heasarc.gsfc.nasa.gov/docs/integral/inthp_archive.html> Steve Drake
ISGRI images (8 energy bands) SPI images ISGRI lightcurves (23-40-80 keV) available in FITS and JPEG HEASARC and INTEGRAL/GOF • Download previews and quick-look data • Multi-band Images, lightcurves, - Roadmap for follow-up analysis
High-level INTEGRAL Products • Routine analysis of all public data • Basic analysis of 600 observations in the archive • ISGRI and SPI lightcurves for 200 bright sources: • “INTEGRAL Bright Source Catalog” • “INTEGRAL Source Results” • ISGRI fluxes in 2 energy bands (23-40, 40-80 keV) • “INTEGRAL AGN Catalog” - detailed information about 68 AGN available soon Steve Drake
