SAS Users Guide and related documentation updated

The Users  Guide to  the XMM-Newton Science  Analysis System  has been
updated  for  SAS  version  12.0   in  order  to  include  the  latest
information on data analysis methods and updated SAS tasks.

The guide  is available from  the XMM-Newton Proposers  Info Documents
and Manuals Web page (Section: Data Analysis) at:


The html version of the SAS Users Guide can directly be accessed under

We remind  that the XMM-Newton SOC provides  additional information on
the XMM-Newton  data analysis through dedicated web  pages, which have
also been updated  for SAS 12  and  which are  regularly updated  when
needed, in particular the third one below (SAS watchouts),

- a repository of "SAS Threads", which are command recipes intended to
  help users  to reduce and  analyse XMM-Newton data.  They  cover from
  the  basic   system  set-up  to  more   complex  instrument  specific
  topics. The threads can be found at:


- the "SAS  Inverse Index", that  allows users to  identify individual
  SAS tasks,  or groups  of tasks,  needed to be  executed in  order to
  perform a given scientific analysis job. The index can be found at:


- "SAS  watchout pages",  where  important issues  concerning SAS  and
  XMM-Newton  data  analysis  are  collected,  along  with  recommended
  workarounds and/or solutions, as well as useful tricks and tips, at:


Update of the EPIC Calibration Status Document

The EPIC Calibration Status Document


has been updated to reflect the status as implemented in SASv12 and in
the calibration  files released alongside  it.  The main  changes with
respect to the previous version describe:

   * the  effect of  the new  SAS  task "epspatialcti"  to calculate  a
     spatially-dependent gain correction in EPIC-pn

   * the implementation of the "time-variable boresight" concept

   * the ELLBETA PSF model as default in the SAS

   * an update of EPIC-pn Long-Term CTI calibration

as well as routine updates  of instrument monitoring results as far as
resolution,    accuracy   of    the    energy   reconstruction,    and
relative/absolute timing accuracy are concerned.

STScI Initiative "Deep Fields: Beyond the HUDF"

The  Space Telescope Science  Institute is  soliciting input  from the
community on  a potentially  important new  initiative

  "Deep  Fields: Beyond the HUDF"

that  can  be  addressed  by  the Hubble  Space  Telescope  in  future
cycles.  One difference compared  to previous  HDF/HUDFs is  that this
time  coordination across  a number  of major  space  observatories is
being attempted.  One such observatory is XMM-Newton. Please note that
no  decisions  in  any  direction   have  been  taken  and  that  each
observatory will decide for itself based on its own rules.  Interested
individuals/groups in the XMM-Newton community may wish to participate
in the formulation of the science  case in general, and for a possible
XMM-Newton participation  in particular. If you want  to contribute to
the formulation of the science case, please consult


Input  should be sent  to the  (Hubble) Deep  Fields Working  Group at
deepfields(at)stsci.edu  with  copy  to XMM-Newton  Project  Scientist
The deadline for this input is 31 August 2012.

Yours sincerely,

XMM-Newton SOC
