Thank you, I hope it will be useful for the GRASS community!

Sure, it works with bands corrected with other software. For instance
before developing i.sentinel.preproc I used arcsi to correct bands (I also
tested i.sentinel.mask with bands corrected using Qgis).
It also works with Sentinel images of the L2A level. If I remember
correctly Stefan told me to have tested i.sentinel.mask with L2A images
obtaining good results.

> Is there maybe a workflow with such data documented in the wiki?

you can find more information and a general workflow about the module and
the developed algorithm in the manual page [0]. Hope this helps!!


kind regards
