= Test Measurements with Closed Lid 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 === bias on or off 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 (you just need to position the telescope, tracking is not needed) in case you want to go to zenith, I recommend something like 2° as directly zenith might be difficult for a real telescope ;) === lid make sure that the lid is closed === configure run in mcp: START e.g. MCP/START -1 100 data (will take a data run of 100 events) === set trigger settings in ftmctrl: STOP_TRIGGER SET_THRESHOLD -1 e.g. SET_THRESHOLD -1 400 START_TRIGGER
