Suzaku News #020: Updated XIS Blank Sky Background Files for AO-2
Prospective Suzaku Proposers,
On Nov 17, the XIS team provided revised versions of the blank
sky background spectra for the 3 FI XIS instruments. The earlier
versions contained the summed data as well as summed exposure times.
Therefore, the count rates in these files were the average of
the 3 FI instruments. This is inconsistent with the ARF files,
which contain the sum of effective areas of the 3 FI XISs.
The new versions are different in that the exposure times have been
divided by 3 (the number of instruments summed). Therefore, they
now contain the summed count rates, consistent with the ARFs.
Revised versions are available via:
Suzaku proposals are due on Dec 1 at 16:30 EST, less than two weeks
