as I was asked already several times how to do these measurements, I put here some information on how to do it

goal of such measurements: record events with closed lid to study what events occur in that case the bias might be switched on of off for these events bias on: probably muon events (they look different depending on the zd, also the rate changes) bias of: only electronics noise triggering

how to do such a measurement

sky position

in case you want to do it not in park position:

in drivectrl: MOVE_TO <zd> <az> (you just need to position the telescope, tracking is not needed)
