To deal with the energy dependence of the grid transmission the grid factor was expanded from a single value to an array and incorporated into the DRM. However this causes inconsistencies for products which do not go through the DRM. This splits the grid factor into an opaque component which is included as the grid factor was previously and an energy dependent correction which is incorporated into the DRM.

  preparing a new release
  stx_subc_transmission: Improved accuracy of message displayed if simple_transm keyword is set.
  Update by Massa, P. - use simplified version of the subcollimator transmission for imaging (temporary solution)
  changed default behaviour of flux keyword
  Improvements to transmission following suggestions from @paolomassa. Value of flux = 1 passed through from  stx_fsw_sd_spectrogram2ospex. Additional description of calculation of  linear attenuation coefficient in stx_subc_transmission.
  stx_write_ospex_fits: fix grid factor recording in FITS file for srm file
  stx_write_ospex_fits: fix grid factor recording in FITS file
  stx_subc_transmission:  added default to calculate low energy approximation if no input photon energies are passed
  fix calculation for single included grid
  fix grid factor rebinning
  remove unneeded lines
  remove commented lines
  Fix ELUT correction for background data
  Fix elut correction factor
  Updated grid transmission to include transparency and corner cutting for pure Tungsten grids following Recipe for STIX Flux and Amplitude Calibration (8-Nov 2022 gh).
  Changes to grid factor to include tungsten transmission
* i4ds:
  Bugfix release
  stx_read_fits : uncommented call to mrdfits to prevent compilation issue when getting version number
