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
Cuts at alpha cut = 15 deg are studied.
- Energy threshold for the analysis
- Source-independent
Cuts at theta cut = 0.2 deg are studied.
- Energy threshold for the analysis
I decide to use only the loose cuts in order to have a low energy threshold.
Spectral results
- Source-dependent
Conclusions: I decide to the cuts gammaness cut = 0.8, alpha cut = 15 deg and intensity = 50 p.e.
- Source-independent
