Current version : | 7.1.2 | Release date : | 14th February 2008 | |
The Science Analysis Software (SAS) is an extensive suite of software tools developed to process the data collected by the XMM-Newton Observatory.
SAS is released periodically. With each release, new software developments and bug fixes are included with the aim to improve the processing of XMM-Newton data.
Within these pages you may find all the information needed to download, install and start using SAS. To proceed, click on the specific navigation link as shown on top of this page.
Before you start surfing through them, you may want to have a look at a very concise SAS description.
To get the fixed package, please download again this package only from the respective subdirectory here, and install it again.
We take the opportunity of having to patch SAS 7.1.0 and include some other changes. The most important one is the change of a default in the EPIC data processing. The temperature-dependent gain correction has been switched on by default within this patch (see CAL-SNR-0223-1.0). The tasks epproc,epchain and epevents all have the parameter withtempcorrection=yes set by default. The correction is mainly useful for EPIC-pn observations which have a non-nominal temperature for the quadrant box electronics. This occurs rarely, for example when the RGS is switched off.
NB: This correction uses the CCF file EPN_CTI_0016.CCF or later. Running the software with an earlier version of this CCF file will produce an empty event file ! So please check that you have updated your CCF directory accordingly !
The correction may be turned off by setting withtempcorrection=no on the command-line.
The full list of tasks included in this patch is:addattribute-2.1, arfgen-1.73.3, backscale-1.3.3, caloalutils-1.104.2, eexpmap-4.2, epchain-8.60.1, epevents-6.42.2, epicproc-2.9.18, epreject-5.9.1, omgrism-1.18.3, rgsframes-3.17.2, rgsproc-1.26.2.
A closer description about what has been fixed and/or changed on each patched package can be found here.
This patch includes eexpmap-4.2 and supersedes therefore the patch released on 03/08/2007
