ARF file extension - FITS auxiliary response file
What is arf file? How to open arf files?
File type specification:
The arf file extension is used for one of the derived formats of FITS (Flexible Image Transport System) format commonly used in astronomy. The ARF is a standard OGIP file format.
The arf file contains the combined telescope/filter/detector areas ("effective area") and the quantum efficiency (QE) as a function of energy averaged over time (and therefore, aspect). The effective area is [cm2] and the QE is [counts/photon]; they are multiplied together to create ARF, resulting in [cm2 counts/photon].
When the input spectrum is multiplied by the ARF, the result is the distribution of counts that would be seen by a detector with perfect (i.e. infinite) energy resolution. The RMF is then needed to produce the final observed spectrum.
