This page explains the steps to obtain the required files to calibrate the GRB221009A data and produce the DL1 files under strong moon conditions I concerns the following data and dates:

  • 2022-10-10: GRB Moon data
  • 2022-10-12: GRB Moon data
  • 2022-11-05: Crab Moon data

Cat-A calibration

This coefficients are produced in the official data tree, as lstanalyser. If you want to run it locally, create your own data tree, with the link to the drs4 time, ff systematics and drs4 baseline directories and a local calibraitand add the option -b "dase_dir_of_your_tree"

2022-10-10:

For this date we must use the pedcal run 10359 taken with the same HV on 2022-11-05. In order to be more flexible, due to the not perfet HV FF of the HV setting, some cuts are a bit relaxed by adding specific parameters to the command line: the command to run is

  • onsite_create_calibration_file -r 10359 --flatfield-heuristic -y "--FlasherFlatFieldCalculator.charge_median_cut_outliers=[-0.9, 3]" "--LSTCalibrationCalculator.npe_median_cut_outliers=[-6,6]"
