- 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
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

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.
