Calculation of JFAC #478

Open rs028 opened 2 years ago

rs028 commented 2 years ago

There 2 main problems with the calculation of JFAC:

  1. zeros or infinite values created by the division (see also #16).
  2. different photolysis rates have different widths (due to different absorption cross sections).

The first is probably solvable with simple modifications to the code (e.g. appropriate threshold for COSX, see #276).

The second requires a different approach and/or a new algorithm to calculate JFAC.

With regard to the second point, this paper https://pubs.rsc.org/en/content/articlehtml/2022/ea/d2ea00072e may be helpful.
