What is the format of the 1D-spectrum .spe files?
This is a little more complex, since it is written as a sequential-access, unformatted FORTRAN file. This means that the hidden fields in the actual physical records on disk are different between VMS and Unix. These hidden fields tell the FORTRAN run-time-library routines how long the records are. You can read and write .spe files in FORTRAN by calling the subroutines read_spe_file.f and wspec.f in util.a / util.olb. The .spe file format is 2 records. The first of these contains information on the spectrum name and length, the second has the data in real*4 format.
