Query: Analysis of the XMM-Newton EPIC Background: Production of Background
  Maps and Event Files   XMM-Newton background maps for the 3 EPIC instruments in their different
instrument/mode/filter combinations and in several energy bands have been
constructed using a superposition of many pointed observations. Event datasets
for the different instrument/mode/filter combinations have also been
constructed, with longer exposure times than previously created files. This
document describes the construction of the background maps and event files, and
their usage. Further details on how to obtain these background products,
together with related software and these explanatory notes can be found at
