Subject: High energy PN cut-off

I'm analysing some XMM-EPIC data - in the PN camera the countrate above 15keV
drops slightly, but continues at good, usable levels throughout the extracted
energy range (specchannelmax=20479, as suggested in the SAS documentation), for
both source and background. However, when I apply a model to this in xspec, the
model plummets to zero above ~18.5 keV, where the data is still usable. The
response files I am using were created for this dataset using rmfgen and arfgen.
IS there any way I can make this hard data usable, or am I forced to ignore it?
I can send plots if required.
