The 'Kappa' correction published in ​https://www.atmos-meas-tech.net/8/3385/2015/ should be implemented in ropp_pp_occ_tool.

  1. Consider if it should be just the simple version (with Kappa = 14/rad), or also considering the findings in ​https://www.atmos-meas-tech-discuss.net/amt-2017-162/
  1. Be aware of the challenge to implement this such that it is included also in the Optimal Linear Combination (OLC) approach to ionospheric correction. The issue there is that the Kappa correction perhaps needs to be made to L1 and L2 separately before the OLC, or perhaps to be applied to the stat.opt BA after the OLC.

A Chapman layer Kappa function was implemented in a new subroutine that could be extended to a more elaborate function along the lines in ​https://www.atmos-meas-tech.net/11/2213/2018/amt-11-2213-2018.html

Implemented with an option so that we are able to exclude the correction for ICDR generation, since it was not implemented in the ROM SAF CDR v1.0.
