The XIS team has released a set of night earth background files for the
preparation of AO-3 proposals. The files are created using the
night erath data released for AO2. The spaced-raw charge
injection (SCI), which is used by default in AO3, reduces the effective
area of XIS by 5.6%. Although this effect is not included
in the night earth background files released here, it is negligible for
the purpose of simulation. Please refer to the AO2
page for details of the night earth data used here.
A gzipped tar file is available for download, containing the following 8 files.
These files can be used simulation purpose only. Please
use with a matching set of RMF
and ARF files.
