Example 8: Finding the cross-region ARF

arfgen crossregionarf=yes spectrumset=spec_output.ds crossreg_spectrumset=spec_input.ds detmaptype=dataset detmaparray=image200.ds

This command returns the effective area in a region of the detector (defined in spec_output.ds) coming from the PSF overflow of flux from the sky region defined in spec_input.ds. The detmaparray, image200.ds, should be an image which includes both detector regions with a pixel size which is small compared to the size of the regions.
