name
   spec: analyse two spectra from the camspec

synopsis
   spec(csdata: in, baseline: in, xyin: out, output: out)

files
   csdata:  contains one spectrum from the Camspec to be used
     as the data.
   baseline:  contains one spectrum from the Camspec to be used
     as the baseline.
   xyin: input to xyplo program
   output: messages to the user

description
   Analysis of spectra produced by the camspec.

   Setup:  Establish communications with the Camspec.

   Give the T command.  If it does
   not respond with '2', use the A command and repeat T until it does.
   This sets the mode to transmittance.

   Then set to 450 nm with           450G
   Check that it is set with         U
   Set to 100% transmittance with    B
   Check that it is 100% with        V
   You can use the O command to do both checks at once.

   Use T and A to set the mode to 0, for reporting in absorbance.
   'AT' should do it.

   Obtain the spectrum with
      xl h
   where x is the interval:
      L 5nm
      M 1nm
      N 0.5nm
   and l is the lower wavelength, h is the high.  Eg,
      L400 700
   scans from 400 to 700 nm with steps of 5nm.

technical notes
   The spectrum is set to -maxint at both ends so that when multiple
   xyin spectra are concatenated, the return lines all run below the graph
   (where you won't see them with xyplo).  Xyplo will object, but ignore it.

   The camspec sends absorbance data multiplied by 100.  This number is
   in constant 'correctionfactor'.
