Here is a list of the current FLAMES/Giraffe data types, their definition,
description, function, and approximate frequency within the Calibration
Plan (if applicable). The first four columns list the content of the FITS
keys HIERARCH.ESO.DPR.CATG/TYPE/TECH and of HIERARCH.ESO.INS.MODE.
DPR.CATG DPR.TYPE DPR.TECH INS.MODE description useful for science
