Alert Information
- Name/type of the alert: Name
- GCN notice:
- Triggered by: Swift-BAT and Fermi GBM
- Alert coordinates:
- RA: 05 42 18 (hh mm ss), Dec: +14 02 00 (dd mm ss)
- RA, Dec in deg (ICRS): 85.577, +14.033
- Alert arrival time: 2022-05-01T19:51:54 (TYPE_INTEGRAL_WAKEUP)
- Other relevant information: We observed Swift-BAT position because the position error was lower than Fermi GBM error.
- Redshift (z):

Analysis
Analysis configuration
- Analyzer: Arnau Aguasca-Cabot (Barcelona Univ., email: arnau.aguasca@fqa.ub.edu)
- Software versions:
- lstchain v0.9.6
- lstMCpipe v0.9.2
- Cuts and parameters used:
- intensity > 50
- gammaness > 0.7
- leakage < 0.2
- DL1 files :
Used DL1a files produced by LSTOSA (lstchain v0.9)
/fefs/aswg/data/real/DL1/20220311/v0.9/tailcut84/dl1_LST-1.Run0{8043-8044}.h5
Since the data taking is in twilight conditions, a tail cut 10 5 cleaning is applied using lstchain_dl1ab.py and standard configuration file from lstchain v0.9.4.
- Random Forest :
src-indep (diffuse gamma, disp_norm) and tuned to run 8044.0000, tail cut 10 5 cleaning.
/fefs/aswg/workspace/arnau.aguasca/Analysis/results/MC/lstMCpipe/models/20200629_prod5_trans_80/zenith_40deg/south_pointing/20220504_v0.9.1_prod5_trans_80_tailcut105_dynclg_tNSBtoGRB220501A_PSF
parameters used to tune the MC files:
"image_modifier": {
"increase_nsb": true,
"extra_noise_in_dim_pixels": 1.801,

"transition_charge": 8,
"extra_noise_in_bright_pixels": 4.557,
"increase_psf": true,
"smeared_light_fraction": 0.125
},
- DL2 MC data for IRF:
