Typical rhot values and optional brightness correction (translated)


My name is Natalya, I am processing images from a small inlad water. The problem is that, when I open the images, already processed by ACOLITE, in SNAP, they come out completely black, I have been told that it may be a threshold problem, due to the excess brightness in the image, which is preventing it from being displayed ; I was recommended to identify such values ​​(rhot and optional brightness for the study area) in SNAP to then insert them in the ACOLITE code and thus achieve a good result in the image analysis, however, I don´t know how to do it, so I request your help.

In advance, thank you very much for your support.
