Full release note for slew configuration 13_prod8.4_20120118.095500
===================================================================
PCMS Infrastructure Version: 8.4
Pipeline Version: 13_prod8.4_20120118.095500
Pipeline Name: slew8.4
Release Date: 2012-01-18
SAS Manifest: xmmsas_20111222_0900
SAS Version: 11.0.0
Summary
=======
This pipeline represents a very minor change with respect to the previous
slew8.4 pipeline (version 12_slew8.4_20111206.111000).
The change is the use of a new SAS ppstrack, xmmsas_20111222_0900, in which the
SAS task, taskmain, only has been updated to v1.91 to solve some memory allocation
problems when treating character strings. This change is driven by the effort to
simplify the process of handing over SSC pipeline processing the the XMM-Newton
SOC.

i. Products Created
===================
The following table summarises all possible product files created by
this slew pipeline.
Product file names are subdivided into components:
Pooooooooooiiseeeccccccbnnn.ttt
where:
oooooooooo is the Observation Identifier.
ii is the instrument.
s is the scheduled flag.
eee is the exposure number.
cccccc is the file identifier given in the table below.
b is the instrument specific field (ISF):
Energy band for EPIC instruments.
OM science window or OM filter code for OM products.
Spectral order for RGS products.
nnn is the hexidecimal source number or 000.
ttt is the file type.

ii. SAS Tasks
=============
The current slew8.4 pipeline uses a public SAS manifest,
(xmmsas_20111222_0900 - see
http://xmm.esac.esa.int/sas/current/documentation/releasenotes/xmmsas_11.0.0.shtml
for details of the SAS task versions and changes relative to the
previous SAS releases). Small changes to the SAS provided in a subsequent
SAS patch release have no impact on the slew pipeline.
iii. Calibration Files
======================
Pipeline processing generally accesses an evolving set of CCFs (current
calibration files). For each observation, a subset of the full set of CCFs
is used in processing that pertains to the epoch of the observation; the
CCF components/versions used are identified in the calibration index file
(PooooooooooOBX000CALIND0000.FIT) that is included in the delivered
observation data product set.
iv. Response Matrices
=====================
In this initial slew pipeline, no source detection and no source specific
products are extracted so the response matrices are not used in the making
of any of the current slew products.
v. Energy Bands
===============
|======|===================|
| Band | Energy Range (eV) |
|======|===================|
| 1 | 200 - 500 |
| 2 | 500 - 1000 |
| 3 | 1000 - 2000 |
| 4 | 2000 - 4500 |
| 5 | 4500 - 12000 |
| 6 | 200 - 2000 |
| 7 | 2000 - 12000 |
| 8 | 200 - 12000 |
| 9 | 500 - 4500 |
|======|===================|
For slew processing, band-specific products are made in bands 6 (soft),
7 (hard) and 8 (total) only.
vi. Energy Conversion Factors
=============================
EPIC energy conversion factors (ECFs) are computed using the instrument
response files for an assumed absorbed power law model with Gamma=1.7 and an
absorbing column density of 3x10^20 /cm2.
In the current slew pipeline, source detection is not performed, hence
source parameterisation is not relevant. ECFs will be included in this section
when source detection is incorporated into the slew processing.
vii. Source Position Rectification
==================================
Source position rectification is not applied in current slew processing
because source detection is not performed.
