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].
For more information check the fits file extension.
This arf file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete.
