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 off: 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)
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 <timemax> <nummax> <runtype>
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 <threshold>
e.g. SET_THRESHOLD -1 400 (setting the threshold to 400 DAC counts
START_TRIGGER
