Item 1.  DO NOT USE PIMMS/XMM-Newton on the CXC website

PLEASE NOTE: the version of PIMMS on the CXC website does not include
the latest update (Sept 2007) of the XMM-Newton calibration for use in A0-7.

If you have already used this version, your count rates will be low by a 
significant amount and will need to be corrected.

Please use the GSFC/HEASARC version of PIMMS to predict XMM-Newton count rates 
for AO-7.
