_________________________________________________________________ ***** ISDC-News 24-NOV-2005 ***** _________________________________________________________________ INTEGRAL Data Analysis Software =============================== Release 5.1 of the Off-line Scientific Analysis (OSA) software package is now publicly available for download at: http://isdc.unige.ch/?Soft+download The OSA package contains the analysis software for the four INTEGRAL instruments (IBIS, SPI, JEM-X and OMC), as well as some generic tools. OSA 5.1 can be easily installed from the compiled binary tar files provided for Linux, MacOS X and Solaris operating systems. The updated Instrument Characteristics (OSA_IC 5.1) shall be used with OSA 5.1. A new version (23.0) of the Reference Catalogue is also available. Changes since the last release: ------------------------------ The main changes compared to OSA 5.0 are: * Improvement of the Graphical User Interfaces for all instruments to allow easy saving, loading and resetting of the parameters used for the scientific analysis. * IBIS/ISGRI: The building of the detector image (i.e. the shadowgram) has been improved in three areas to better handle difficult situations (bright source at border of the field of view, missing context and module switches affecting ~30% of the pointings). Another change is the new ability to handle spectra requiring different Ancillary Response Functions (ARFs) to prepare for the forthcoming release of three new ISGRI ARFs. * JEM-X: The gain fitting and correction module was updated to handle difficult situations. The gain correction should now be accurate within 3% for all pointings. The image mosaic tool has also been updated to allow more flexibility to the user. * IBIS/PICSIT: A bug in the image mosaicing tool causing a problem in the source positions was fixed. The spectral extraction has been improved but is still quite unstable. * Instrument Characteristics: 17 files have been updated compared to OSA_IC 5.0. For JEM-X, in particular, there are new response matrices and a better model for the evolution of detector non-uniformities. * Reference Catalogue: Many source positions have been updated and new sources added.

The re-processing of the data available in the archive with the latest version of the Off-line Scientific Analysis software (OSA 5.1) is ongoing with the following priority: 1) Inclusion of SPI scientific results (result checking) 2) Update of JEM-X results with OSA 5.1 (to start now) 3) Inclusion of PICsIT results (started with lower priority) 4) Update of ISGRI results with OSA 5.1 OSA Documentation ================= Scientific Validation Reports for OSA 5.x are now available for all instruments. There are also updated documents for SPI analysis of Gamma-Ray Bursts. A new document provides a detailed cross-calibration report for the high-energy INTEGRAL instruments. These documents are all available at: http://isdc.unige.ch/?Support+documents _________________________________________________________________ |
