Overview

  • Source-dependent/independent analysis using LSTCHAIN v0.9.4 (MC production processed with LSTCHAIN v0.9.3, R0 to DL1 process by LSTOSA using LSTCHAIN v0.9.2)
  • Cleaning method tail cut 84 and dynamic cleaning. Also, the MC files are tuned to match the NSB in the FoV and the PSF.
  • Observations used in the analysis:

Monte Carlo information

  • Link to MC files used:
- Particle types: gamma off0.4deg, proton
- ZD (deg): 40
- AZ (deg): 180
- Other information: MC production through PR in lstMCpipe Github webpage (https://github.com/cta-observatory/lstmcpipe/pull/185)
- MC files are tuned to match the NSB in the FoV and the PSF.

DL1 data

  • Processed with LSTOSA using LSTCHAIN v0.9.2.
- Dynamic cleaning and tail cut cleaning with pedestal threshold applied by the the standard parameters using pipeline LSTOSA.

Crab Check

Run selection using Crab_data_selection_notebook: https://indico.cta-observatory.org/event/3984/contributions/32878/attachments/20998/29572/Crab_data_selection_notebook.pdf

Threshold for the rate30_mask is set to 4.3. I exclude run 6016 because I obtain a strange SED at low energies.

Data reduction Specifications

  • Source-dependent

SNr sig diff ghc ac.png

Cuts at alpha cut = 15 deg are studied.

  • Energy threshold for the analysis
  • gammaness cut>0.6 and alpha cut<15 deg, int>50 p.e.
  • gammaness cut>0.7 and alpha cut<15 deg, int>50 p.e.
  • gammaness cut>0.8 and alpha cut<15 deg, int>50 p.e.
  • gammaness cut>0.9 and alpha cut<15 deg, int>100 p.e.
  • Source-independent

SNr sig diff ghc tc.png

Cuts at theta cut = 0.2 deg are studied.

  • Energy threshold for the analysis
  • gammaness cut>0.6 and theta cut< 0.2 deg, int>50 p.e.
  • gammaness cut>0.7 and theta cut< 0.2 deg, int>50 p.e.
  • gammaness cut>0.8 and theta cut< 0.2 deg, int>50 p.e.
  • gammaness cut>0.9 and theta cut<0.2 deg, int>100 p.e.

I decide to use only the loose cuts in order to have a low energy threshold.

Spectral results

  • Source-dependent
  • Loose cuts, 20 November 2020. 2 bins per decade
  • Loose cuts, 20 November 2020. 2 bins per decade
  • Loose cuts, September 2021. 2 bins per decade
  • Hard cuts, September 2021. 2 bins per decade
  • Loose cuts, March 2022. 2 bins per decade
  • Hard cuts, March 2022. 2 bins per decade

Conclusions: I decide to the cuts gammaness cut = 0.8, alpha cut = 15 deg and intensity = 50 p.e.

  • Source-independent
  • Loose cuts, 20 November 2020
  • Loose cuts, September 2021
