Description

FRMF is a file-based RMF model that represents the redistribution matrix which maps photon energy to, e.g., PHA bin.

Note that in Sherpa analyses, the energy-space binning of the RMF (found typically in the ENERG_LO and ENERG_HI columns of the MATRIX extension of the RMF file) does not have to match the analogous energy-space binning of a matching ARF. (This is also true if instead of energy, the RMF is defined as a function of wavelength.)

See the documentation on the INSTRUMENT command. See also the RSP and FARF1D instrument models.
