• Rounds up rebinned pixel size to the nearest integer multiple of the elementary size of the input image

• Ignores pixels on the edges that do not fit in an integer number of rebinned pixels

• The ancilliary response file for the output spectra should be created with SAS task arfgen. When dealing with filter masks, arfgen works by averaging the ARF in a number of grid elements on an internal map, thus, it is necessary to allow a large number of elements in the internal arfgen map:

  arfgen spectrumset=specfl0.fits arfset=specfl0.arf extendedsource=yes detxbins=100 detybins=100

• Temporary files are created with the names specified in the parameters tmpsrclistset, tmpbkgregionset, tmpflatset, tmpposmaskset, tmpnegmaskset, tmpposspecset, tmpnegspecset, and are deleted when they are no longer needed, at the end of the task.
