Good afternoon to everyone, this is more a theorical question but as it regards the SNAP processors, I hope I can find some good answer here.

I would like to use the processors related to water quality, chl concentrations etc etc like the C2RCC for S2 or MPH/FLH for S3 , but as I am not a specialist about these topics.
I have seen that using these processors for each sensor there is a set of default parameters and I would like to know in which case the default settings should be modified. I have tried some tests and I do not know if the results are correct or not. Can I provide them here for an opinion?
