Access to the XMM data archive

Access to the XMM Data Archive is facilitated via the XMM Archive Management Subsystem (AMS). It can be accessed in different ways:

• Query via a web interface,

• request CD-ROM delivery of the entire data for a certain observation, including ODF, CCF, (calibrated) event lists etc. and the PPS data products,

• download constituents of the former, which have been flagged in the AMS as downloadable,

• obtain an updated CCF. (TBC)

Access is gained via the following mechanisms:

• Queries, e.g., of the proposal database (for example for accepted or executed observing programmes), are processed via the AMS web interface.

• PPS data products can be requested via the AMS interface. They will be staged in a public area, from where they can be downloaded.

• Requests for CD-ROM shipments are submitted via the AMS interface. Users requesting CD-ROMs must register first, if not yet registered as an XMM user from submitting an observing proposal.

• In case a complete, new CCF should be required, delivery is via a CD-ROM. However, those constituents of XMM CCFs which can be expected to change relatively frequently will be made available via ftp (requests being submitted through the AMS web interface). (TBC)
