Detecting an Herschel-HIFI FITS

A FITS file fed as input of the command LAS$\backslash$FITS is assumed to be an Herschel-HIFI FITS if the Primary HDU:

  1. contains the card HCSS____, and
  2. the value of the card TYPE is not HICLASS nor `Class formatted fits file'.
The 2nd rule discriminates Herschel-HIFI FITS and CLASS FITS produced by HICLASS.
