• Analysis by A. Aguasca-Cabot (Universitat de Barcelona - arnau.aguasca@fqa.ub.edu)

General information

This wiki web page shows the analysis of GRB221009A data recorded in dark conditions (run_id: 9625-9960) and in mild moon conditions (run_id: 9629 and 9630) using the source-independent analysis.

For the analysis of GRB221009A for runs in moon conditions go to the following page: GRB221009A_src-ind_analysis_moon

The wiki page with the summary of the current results of the src-ind moon analysis (as of February 8th) for the discussion with LST-Reco conveners is the following: [1]

Monte Carlo information

• Link to MC files used: /fefs/aswg/data/mc/DL1/AllSky/20221027_v0.9.9_crab_tuned/*
  • Particle types: The standard ones for the AllSky MC production.

DL1 data

No reprocessing of the real DL1a data was required, only NSB tuning was added to the MC files. DL1a files produced by LSTOSA (lstchain v0.9.6?) and lstMCpipe (lstMCpipe v0.9.0 using lstchain v0.9.9).
