- Version 15.0 of the Science Analysis System (SAS) released
- Distribution of 32-bit versions of SAS to be discontinued
Version 15.0 of the Science Analysis System (SAS) released
The XMM-Newton SAS team is pleased to announce the release of a new version of the SAS: SAS v15.0.
Binaries for diverse flavours of Linux and MacOs (in 64-bit native versions) and one Linux 32-bit version are available at
The main improvements of this release can be summarised as follows:
Correction of the conversion between celestial and detector coordinate systems.
Due to a long-standing error in the task attcalc, the Euler Psi angle contained within the boresight calibration file had the wrong sign. In practically all cases the two errors cancelled out yielding a correct astrometry reconstruction within SAS. However, direct use of the boresight numbers resulted in wrong conversions. This upgrade requires a new calibration file, XMM_BORESIGHT_0026.CCF.
- The new task ebkgreg determines the most suitable position of the background region for any source in an EPIC-pn image.
- The new task eupper calculates, given a position in celestial coordinates, the count rate upper limit for any sky image regardless of the instrument.
- eboxdetect, the task for slide box source detection, accepts input data in detector coordinates.
- The metatask for slew data analysis eslewchain can produce PNG files for each subimage.
- RGS responses can be derived by rgsrmfgen in separated files: a redistribution matrix (RMF) and a corresponding Ancillary Response File (ARF).

Distribution of 32-bit versions of SAS to be discontinued
Differently from previous releases of SAS, this time only one 32-bit version is distributed.
As announced in a previous issue of this Newsletter ( #158)
the distribution of SAS in 32-bit binary versions will probably be discontinued in all future releases.
