Here is the log file as well as two user settings files for previous runs

Dear Quinten Many thanks for the link to that paper and I also saw your paper in Optics Express Yes I would like to keep on trying to find the solution Here are the last run text files acolite_run_20221022_193732_l2r_settings.txt acolite_run_20221022_193732_l1r_settings_user.txt acolite_run_20221022...

Dear Quinten I have tried varying the glint mask band between red (666) and NIR (707) many times as well as trying different glint mask thresholds but each time the result is no different. The glint corrected outputs are all the same no matter which setting I use, and the glint corrected images are ...

Hi Quinten The output you got looks good However when I try to set the glint_mask_rhos_wave=866, Acolite fails to run acolite_run_20221022_193732_l1r_settings_user.txt When I do not set it, I do get an output but the glint corrected image is brighter than without glint correction To get that output ...

Hi Quinten Yes, in the new image I do see the same spectral shape as in the earlier post, with high NIR and low red I tried setting the glint force band to 666, but the result is the same as without glint correction. I attach the user settings file acolite_run_20221022_193732_l1r_settings_user.txt A...

Dear Quinten I have tried another image but got the same result. I take your comment (Oct 26th) "After glint correction in this scene the red band tended to go negative so I changed l2w_mask_negative_wave_range=400,600" As I need to obtain LWR in the NIR for mapping mixed seaweeds, this ba...

Hi Quinten
No- the date is not crucial - will try another date and get back to you

Hi Quinten Thanks so much for helping solve the glint correction problem. The image outputs you posted look very good, so I don't know why I cannot get similar result I have tried the methods you suggest, as well as varying the settings- The last attempt acolite_run_20221022_193732_l1r_settings_user...

OK - I just saw your latest post so you may ignore mine just sent- will try and let you know

Dear Quinten I tried all your 3 suggestions both alone and together I found that only changing the line l2w_mask_threshold from 0.0215 to 0.15 - does work (but changing it to 0.1 did not work) acolite_run_20221022_193732_l1r_settings_user.txt As I'm trying to map marine habitats I also need to do gl...
