FLIX: Flux Limits from Images from XMM-Newton
FLIX is an upper limit server for XMM-Newton data, provided by the
XMM-Newton Survey Science Centre (SSC).
2013 Oct 16: a version of this program using the data corresponding to the 3XMM (DR4) catalogue is now available for experimental use. It has not yet been tested thoroughly so be cautious in using the results. Follow this link:
Flix for 3XMM.
If you provide a position of interest on the sky (or a text file with a list
of positions) FLIX scans the public data products from XMM-Newton to determine
whether each point was observed. If so FLIX:
Results are returned in the form of HTML tables and as a downloadable FITS file.

FLIX help file
- Estimates an upper limit to the X-ray flux at that point in various energy
- Provides a crude estimate of the actual flux within a circle centred on that point,
- Scans the
2XMMi catalogue listing any detections within 2 arc-minutes, and
extracts a thumbnail X-ray image centred on the point.
