higstract

  higstract (extract/grep/select) line parameters from a spectroscopic data base file

  usage:
  higstract  [options]  line_parameter_database

  command line options:
    -h            help
   --help         help extended
    -c   char(s)  comment character used in output file (default #)
    -o   file     output file (default: standard output, see last note of extended help)

    -f   string   output format:  original or simple lists (position vs strengths etc)
                                  default "vSEan" (see notes of extended help)
    -i   integer  isotope name (e.g. 4 or 162 for heavy water HDO, the fourth most abundant isotope)
    -m   string   molecule name  (one molecule only!)
                  "main" to save only lines of the main molecules (ignore trace gases)
    -S   float    minimum line strength to accept
    -x   interval lower and upper end of spectral (default: wavenumber) range (comma separated pair without blanks)
    -X   string   unit used for setting spectral range with -x option (does not affect output listing!)
                  (default: "cm-1",  other choices: "Hz", "MHz", "GHz", "THz", "mue", "nm")

  NOTE:  to avoid name clashes with numpy's extract function,
         this module and its the 'main' function have been renamed to 'higstract'
	 (short for HItran-GeiSa-exTRACT)
