I have a question about light pollution calculation.

I've installed newest DIALux 13.0, where is calculation of obtrusive light added. As per explanation on your websites, I've concluded that is what I need for a specific project I'm working on. I was wondering if you can just clarify something for me.

FHS of the calculation object in the specific project needs to be under 5%. When I had calculated that obtrusive light, it showed 4 values (as it is shown in the picture). Can you just tell me which one of those 4 is FHS and how could it be changed (improved) or how to manipulate with it?

Thanks in advance!
