Set the parameters for SEN2COR

Hello friends.
I have read the Sen2Co Configuration AND User Manual document and explained some (not all) of the settings for atmospheric correction, but I still have problems setting up the atmospheric correction parameters.
Can anyone help me?
I dont know what these settings are and what their wrong choice will affect the results.
thank you

why don’t you ask more specificly in your original topic?

The clearer the question the more likely is someone to answer.
