Caution is urged before rbnrmf is used.
The primary use of the task is likely to be to compress RMF datasets in channel-space such that the resultant number of channels matches that in a given PHA dataset. Hence downstream spectral analysis packages can be used to unambiguously map the channels in the PHA spectrum and Response matrix. The non-linear compression modes available for use with ASCA SIS data should be used with extreme care. These rbnrmf modes are only required if users wish to perform spectral analysis on a PHA dataset taken in one on-board datamode in conjuncture with a detector response designed for use with PHA data obtained in the other datamode.
