fevpbtoa -- Converts Comptel EVP fits files to an ASCII file.
fevpbtoa fitfile frec nrec scal
This utility converts Fits formatted COMPTEL EVP data files to an formatted ascii file.
The input fits file is opened. The output ascii file "ascfit.evp" is opened. Beginning at "frec", "nrec" events are transferred to the ascii file. Application of column scaling factors is performed when scal = true and suppressed when scal = false.
(The output structure is based on the routine SEVPBTOA written by Rita Freuder at the University of New Hampshire, that uses the native data on a SUN computer.)
