Overview[edit]
- 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:

Analysis results[edit]
- High level analysis performed with gammapy-v0.19
Alpha plot[edit]
- Filters in EventSelector applied:
"EventSelector": {
"filters": {
"intensity": [50, Infinity],
"width": [0, Infinity],
"length": [0, Infinity],
"r": [0, 1],

}
}
See section Crab Check to know more about the justification of the applied cuts. Stacked alpha plots:
Daily alpha plots:
- Energy threshold for the analysis
Theta plot[edit]
Stacked theta plots:
Daily theta plots:
- Energy threshold for the analysis
Spectral results[edit]
- Source-dependent
- Daily SEDs
- HESS and MAGIC comparison
- Daily MAGIC/LST-1 SEDs:
- Source-independent
- Daily SEDs
- HESS and MAGIC comparison
No daily SED can be plotted because the SED from LST-1 using gc=0.6 and tc=0.2 deg are not reliable.
Light curve results[edit]
- Source-dependent
- Source-independent
- - Notice that since the daily SEDs with quality cuts (gc=0.6 and tc=0.2 deg) are not reliable, the daily flux are computed with the stacked SED using data between 20210809-12!!!
- - No comparison with MAGIC light curve is done because the energy threshold using (gc=0.6 and tc=0.2 deg) is higher than 100 GeV.
Crab Check[edit]
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[edit]
- 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[edit]
- Source-dependent
Conclusions: I decide to apply the following cuts: gammaness cut = 0.8, alpha cut = 15 deg and intensity = 50 p.e.
