Research direction

Start with the linked Rayleigh correction documentation and its example programs; the issue does not name repository files or tests. Determine whether raw GeoKOMPSAT-2A band data is supported, explain the four correction values and whether correction applies before image compositing, and document the resulting workflow if appropriate.

Written by the indexing model from the issue text.

Description

I have read the page at https://pyspectral.readthedocs.io/en/latest/rayleigh_correction.html
but as I am new to this, I still need to do further reading and look at example programs.

I have raw geokompsat 2A images for each band and wonder if the rayleigh correction in Pyspectral can help me perform atmospheric correction before combining into the RGB image.

Reading the documentation, it outputs the correction factor (of which there are 4 values in % - why are there 4 values?) which needs to be subtracted from the raw data.

I guess this process can only be done at data level and not at image level?
