ATCOR4 Batch Changes Visibility

[FCarotenuto]

Thank you for your quick reply, but I'm still confused. I thought that, when running in batch mode without a GUI, the .inn file is the only way of setting the processing values (altitude, heading, solar angles, visibility, atmosphere, etc. etc. etc.), so, if I input a negative value in there won't ATCOR use that as the visibility instead of the value I want? Or does ATCOR uses the absolute value and reads the sign as a sort of flag?
Maybe am I mistaken about inputting these values for batch and there are other command line options to set them?
