Trigger threshold #36

Open moralejo opened 2 years ago

moralejo commented 2 years ago

The current LST1 camera trigger threshold simulation seems to be too high for quite a few of the LST1 data we have collected. I think the relevant setting is this one (but please experts step in if needed):

https://github.com/cta-observatory/lst-sim-config/blob/347027c1d28f2f361cf777470701ed9ace04a022/LST1.cfg#L165

We would like to have another version of the simtel files, with significantly smaller threshold, so that all the recorded events in the real data are represented in the MC. Tentatively we would like to have a value asum_threshold = 170. It would be enough to first launch it for the test MC in node_theta_10.0_az_248.117_ so that we can check if the value is reasonable.

Hi @moralejo at /home/georgios.voutsinas/ws/AllSky/TestDataset/Crab/sim_telarray/node_theta_10.0_az248.117 you can find 2 directories: threshold_170 & threshold_370 where you can find the simtel simulation with the corresponding threshold. It is quite straightforward to scan a number of threshold values, if you think it can be useful.

Thanks a lot @Voutsi ! I will check these and let you know.
