XMM-Newton SAS V5.1 Scientific Validation and Data

SAS V5.1 Scientific Validation

This page contains the Scientific Validation Report for SAS V5.1 (.ps.gz) as well as the data use for this validation.

The SAS Science Validation (SV) 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 the science validation report, 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.

Previous Scientific Validation (SAS V5.0)

The SAS V5.0 Scientific Validation Page can be found here.

Updated Documentation

Two documents have been updated w.r.t. the documents available in the SV V5.0 page. These updated documents are:

• Data Files Handbook (Issue 2.2).
• ODF/SDF Interface Control Document (Issue 2.9).

Available Data

The following datasets have been used for the Scientific Validation of SAS V5.1. The number of datasets available has significantly improved (8) with respect to the previous SV set (V5.0) showing an improved performance of the SAS release.

The data information is provided in line with the Public PV data using a condensed table with the most relevant information on the datasets and links to the specific files (ODFs) or directories (PIPEs).

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.

A complete list of all SV2 data files along with their sizes can be retreived in this README file.

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.
