A..3.2 Upper Limit Server

The FLIX utility under the link
http://www.ledas.ac.uk/flix/flix.html
can be used to check, for a given sky location, whether XMM-Newton has observed that region of the sky and if so, determine XMM-Newton upper limits, X-ray fluxes, and create image cut-outs.

Alternatively, the XMM-Newton Upper Limit Server can be used:
