Here we list several web services which may be helpful for doing research with the XMM-Newton data.

Flix upper limit server

Currently available only for 3XMM-DR7 subset of data: https://www.ledas.ac.uk/flix/flix_dr7.html

TAP (Table Access Protocol) server

TAP server at CDS VizieR allows you to do large scale cross-matches of your source lists with the XMM-Newton catalog (sources table only): 3XMM-DR5, 3XMM-DR6, 3XMM-DR8. Alternatively, in a TAP client of your choice (TOPCAT is a very good option) enter service url http://tapvizier.u-strasbg.fr/TAPVizieR/tap and then use "IX/46/xmm3r5s" for the 3XMM-DR5 sources table name, "IX/50/xmm3r6s" for the 3XMM-DR6 sources table name or "IX/55/xmm3r8s" for the 3XMM-DR8 sources table name.

XCatDB

The SSC provides another Web interface based on SAADA and named the XCatDB (http://xcatdb.unistra.fr). Its main features are:
