Kstars-devel Digest, Vol 229, Issue 20

[joseph.mcgee at sbcglobal.net]

Hi again,

I managed to get a simple filter compensation mechanism working in the 
exposure calculator. I created a separate shared folder for this version:

https://drive.google.com/drive/folders/1uvpFJvHVOhT_2gqCjB_uQ_wL2Jpn0Dho?usp=sharing

To try the filter compensation you would just edit the filter bandwidth 
value in the calculator.  For unfiltered the value would be 300, (as a 
full bandwidth).   For an R, G, or B filter a value of 100.  For an S, 
H, or O narrowband, you can try 5 (for a 5nm filter), or 3 (for a 3nm 
filter).

The application of the filter adjustment is simply applying a factor to 
the light pollution noise calculation.  I'm not convinced that this is a 
true representation of the mechanics. But I found a few other posts on 
cloudy nights that seem to use this approach with Dr Glover's equations.
