Item: letgD1996-11-01gr[eff|err]N0001.rdb
Description: Diffraction effective efficiency file for mirror-weighted
  shells.
  2 files = efficiencies and errors
    LETG_effic[_err].rdb
  These are the efficiency files used for the AO-1 release.
  Notes:
    - the HRMA area weighting was done using the HRMA
        areas supplied by read_effic.pro: the files
        hrma_1.dat etc (now in !DDIDL/lookups/).
