Version 14.0 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 v14.0.
Binaries for diverse flavours of Linux and MacOs (both in 32- and
64-bit native versions) are available at
The main improvements of this release can be summarised as follows:
A number of upgrades in the calibration of this instrument have been
* An energy-dependent correction to the CTI is now applied, and the
time dependency has been updated, to represent better the observed
* The dependency of the spectral energy resolution on time and pattern
has been introduced. This change implies that EPIC-pn response
matrices are now time dependent
* Changes improving the accuracy of the energy scale in the fast modes
have been included, that apply differently to the different modes.
To make their use easier, the new parameter 'withdefaultcal' (with
default 'yes') has been introduced in both 'epproc' and
'epchain'. Also, the systematic offset in the energy scale of
single- and double-event spectra is now corrected by 'epevents'
* A new task for soft flares flagging, 'eprejectti', replaces
'epreject' for EPIC-pn Timing mode data.
* An empirical correction to improve the cross-calibration of the EPIC
effective areas has been introduced as a new option in
'arfgen'. Since the calibration is still preliminary, currently its
use is only recommended as a tool to estimate the impact of
effective are inter-calibration uncertainties. It can be used
through the non-default parameter 'applyxcaladjustment'
* The new metatask 'eimagecombine' produces combined smoothed,
background-subtracted and exposure corrected EPIC images. This task
uses as input the individual sets of images from the, also new, task
* The heliocentric and solar aspect angle corrections to the
wavelength scale are applied by default.
* A general upgrade of many tasks has taken place, corresponding to
the developments leading to the OM catalogue.
* The OM SAS interactive tasks for manipulation of source lists,
'omsource' and 'omgsource', run now flawless in the 64-bit SAS
* 'omfchain' processing of OM fast mode data now extracts correctly
the background from the associated image.

Data Analysis Threads for SAS v14.0
SAS analysis threads have been revised to ensure compatibility with
SAS v14.0. Small updates as well as some cosmetics have been

Let us know about XMM-Newton related Ph.D.
The XMM-Newton team is collecting information about the completion of
doctorates and Ph.D. theses based on (or making use of) XMM-Newton
observations. Ideally, it is our intention to collect the complete
list of Ph.D. works based on XMM-Newton data and this is why we need
We would appreciate if you - being a candidate or supervisor of a
doctorate - could let us know the following details:
- Year of the thesis
- Candidate's name
- Supervisor's name
- Thesis Title
- Statement that the thesis is either based on, or making use of,
