Measuring lamp warm-up times for FCU light sources

scripts live in ​svn+ssh://cetus/svn/astronomy/analysis

This script had a significant re-write in March 2022, and now uses the ACQ camera to measure lamp brightness instead of the LRS2 instrument.

The script measure_warmups.py will take a series of exposures on the ACQ camera after powering on each light source to watch its flux change as it warms up.

You should run it like this to test all lamps, which should take about 20 minutes:

measure_warmups.py -graph

To stop this script, simple touch a file called "stop" in the same directory where you are running it:

touch stop

and it will stop after the current exposure ends.

If you select the -graph option, then the results of the warm-up test analyzed and saved in /data1/archive/fcu_warmup/

After you run this script please email SJ with details about what you did so we can analyze the warmup time measurements.
