arfgen spectrumset=spectrum.ds detmaptype=psf
Generates a dataset ancillaryfile.ds. The effective area, filter transmission and quantum efficiency curve are included in the ARF.
A point source located at the centre of the source region described in the data subspace within spectrum.ds is assumed. An encircled energy correction is applied (section 5.5). Corrections are applied for any CCD gaps or source region area falling outside the field-of-view or observing window but not for bad pixels or bad columns.
The ARF is emission-weighted using an internal detector map based on the PSF. The map is rectangular-shaped, and has a weighting which falls off with distance from the source in line with the PSF.
