Spectral results[edit]

  • Source-dependent
  • Stacked SED (Aug 9-12)
Daily SEDs
  • 20210809 SED
  • 20210810 SED
  • 20210812 SED
  • HESS and MAGIC comparison
  • HESS/Fermi and LST-1 SED.
  • MAGIC and LST-1 SED (Aug 9-12).
Daily MAGIC/LST-1 SEDs:
  • MAGIC and LST-1 SED (Aug 9).
  • MAGIC and LST-1 SED (Aug 10).
  • MAGIC and LST-1 SED (Aug 12).


  • Source-independent
  • Stacked SED (Aug 9-12)
Daily SEDs
  • 20210809 SED
  • 20210810 SED
  • 20210812 SED
  • HESS and MAGIC comparison
  • HESS/Fermi and LST-1 SED.
  • MAGIC and LST-1 SED (Aug 9-12).

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
  • HESS/Fermi and LST-1 light curve.
  • MAGIC and LST-1 light curve.
  • 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.
  • HESS/Fermi and LST-1 light curve.


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

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[edit]

  • Source-dependent
  • Loose cuts, 20 November 2020. 2 bins per decade
  • Hard 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
  • All runs. 4 bins per decade

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

  • Source-independent
