SAS V5.0 Scientific Validation
Each SAS release is accompanied by a set of "test data", which allow any
SAS user to personally evaluate the quality of software and
calibrations. All SAS releases
(and the corresponding PPS products) are
scientifically validated on each of such test datasets.
The scientific validation aims at
ensuring a constant and properly documented high quality of the
SAS. The main goals of the science validation are
therefore to test:
- which instrumental modes are fully supported by SAS,
- which scientific products SAS can produce, and
- the level of accuracy associated with those products.
The outcome of the SAS v5.0 science validation for each test
dataset is summarized in a report, available along with
the dataset.
The SAS science validation is an intrinsically open process, mainly
driven by the need of the SAS user community. If you have any
questions on the results reported in one of the science validation
reports,
or if you would like to suggest possible additional tests (or the
results of tests you have performed), do not hesitate to
contact the
XMM-Newton helpdesk.

SAS v5.0 Scientific Validation Data
The data available from this location is the set of standard XMM-Newton data
(ODFs and Pipeline Products) used for the SAS v5.0 Scientific Validation.
Data Status
| First data set was made available on: |
2000-12-27 (Lockman Hole) |
| Second data set was made available on: |
2001-01-22 (G21.5-09) |
| Latest data set has been made available on: |
2001-01-31 |
| Additions made in this update: |
Mkn 421 (data and SV report) |
Note: The availability of the different data sets will occur in staggered
deliveries. Links in the data section will become active when data or
information for an observation is available. Please, check this page from
time to time to see latest updates.
Data Processing
The datasets comprise an ODF and a set of Pipeline Products. The ODFs are
produced from the spacecraft telemetry by the SOC. Further processing to
produce the Pipeline Products is performed on behalf of ESA by the
XMM-Newton Survey Science Centre,
an independent team comprising a consortium of nine institutions in four
countries (UK, France, Germany and Spain).
Relevant XMM-Newton links
You can also find the data at the
XMM-Newton NASA mirror site.
Data format
For a description of the ODF/SDF format and the PIPELINE Products refer to:
- The Data Files Handbook provides a description of the different
files generated by the XMM-Newton systems;
(current issue is 2.0, compliant with SAS v5.0)
(postscript or
pdf)
- ODF/SDF Interface Control Document (current issue is 2.8);
(postscript or
pdf)
- Data Products Interface Control Document (current issue is 2.1);
(postscript or
pdf)
- SSC Data Products Specification (current issue is 1.1);
(postscript)
Data Download
Data can be downloaded from the provided links in each Observation's section or
directly accessing the anonymous
XMM-Newton ftp site.
The data are wrapped as:
- ODFs: tar.gz of all the ODF constituents. After decompresion and
untar all ODF constituent files are already available as individual files.
Data in this final form is suited for SAS processing.
Note: The average size of an ODF (tar.gz) is ~150 Mbytes and
usually range between 100 and 250 Mbytes.
- Pipeline Products: Each Product Group is available separately as a
.TAR file. Each one of these .TAR files contains a full Product Group
with the constituent data mostly as compressed (.FTZ) files. In addition,
each Pipeline Product contains an .ASC file providing a top level
description of the Observation.
Remarks: The size of the Pipeline Products Groups ranges from less
than 1 Mbyte to a few 100's of Mbytes. In those cases where the size of
a Product exceeds 200 Mbytes it has been tried to split it in more than
one .TAR set to decrease the download size
(those cases can be recognized by the _N extension to the name).
Please consider the possibility of using a recovery/recursive download utility
(e.g.: wget, available and described at the
gnu web site)
if your link has problems with the big files.
Available Data
The following objects have been observed and constitute the reference data set.
Data availability for an object is marked with an active link or checking the
Data Details section below.
Data details and access
The following entries provide the original scheduled details for the observations of the Science Validation Data Set. The actual execution may render slightly different values (e.g.: observation duration).
Each entry lists the following parameters:
- Obs Id: Observation identifier.
- Target Name: As given in the Proposal.
- RA and Dec: Coordinates as given in the Proposal (Epoch: 2000).
- Start and End Times: Scheduled UT for the start and end of the Observation.
- Obs duration: Scheduled duration in seconds (i.e.: End - Start).
- Rev: XMM-Newton Revolution number when the Observation was scheduled.
- Prime Instr.: Prime Instrument (to which the coordinates refer).
- Comments: Any comment of interest about the data. This section contains
also a link to the Scientific Validation Report.
- Download: Allows the download of the data (if link active). Refer to the Data format section for details on the form in which the data are downloaded.
