Which detection area is taken into account?

[153957]

It is unclear (to me) from the code which area is taken into account.

Only the detection area around the station where the first (main) shower hits, or also where the second shower hits?

Possible places in code where it is taken into account:

DetHisparc.cpp:

double DetHisparc::TotalArea() const {...}

However, the TotalArea is ignored in other scripts.

Detector.cpp:

double Detector::EffectiveArea(...) {...}
double Detector::SecondDetectionProbability(...) {...}
