The online display automatically writes a CLASS
spectrum for each OTF dump into the SPECTRA.SMT file.
A future UNIX version of CHEF will write each OTF
row or column as one entity (like at the 30m telescope)
but the old VAX version of the Grenoble Software
(of 1994) does not yet have this feature.
Because of the amount of data, the spectra are not displayed in the online
CHEF window. It is, however, immediately accessible in the SPECTRA.SMT
file. We may later add a display for a spectrum integrated over the whole
scanning axis to give some feedback for the astronomer.
