XMM-Newton Science Archive (XSA) version 2.7 now online


Version 2.7 of the XMM-Newton Science Archive (XSA) is now available at the following location:


This version includes several improvements and new facilities, among them being:

  • filtering on high particle-background intervals can be applied upon the interactive generation of EPIC spectra from a cursor-defined position in an exposure field-of-view, or to the screening of an event list. The screening is applied by generating Good Time Intervals from the single-events, 10-s time-binned field-of-view, light curve. The minimum energy of the light curve (nominally 10 keV) and the count rate threshold applied to the light curve (nominally 0.35 cts/s and 1.0 cts/s for the MOS and the pn, respectively) are customizable by the user.
  • A compact list of the EPIC sources detected by the PPS pipeline is available by clicking on the "Details" button beside each observation-record in the archive. Parameters such as position, count rate, PSF, vignetting and background correction at the source location, and detection probabilities, are shown.
  • Any queries or results can be saved to a file. Saved configurations can later be uploaded into the XSA user interface.
  • A "Back"/"Forward" button allows the user to browse through the queries (and the results or queries) performed during a given XSA session.
  • Users can perform queries on a set of data processing configuration items, such as:
    • the version of the ODF available in the XSA database, through the version of the ODS system employed to generate it
    • the SAS version employed to generate the PPS products
    • the date of the PPS processing (through the date of the Calibration Index File generated by the pipeline)
    • the PCMS version employed to generate the PPS products.
  • Users can now monitor the status of their shopping basket download or data processing requests through a "Request Monitor" tool, which can be launched via a button in the top panel of the XSA user interface
  • a list of "instrument events", generated during the real-time operations, is now available from the "Details" page of each observation record.

A short "guided tour" of the XSA is available at the following location:
