Comparison with the SED from the performance paper (after correcting by EDISP):
Energy dependent cuts (0.8 gammaness, 0.7 theta), interpolated IRFs
Lightcurve
Lightcurve above 100 GeV
Energy dependent cuts (0.8 gammaness, 0.7 theta), interpolated IRFs
F=(5.868 土 0.082)e-10 cm-2 s-1
Consistent with the performance paper. As shown by this paper, the flux measured by LST-1 is slightly
higher (~10%) than that from the MAGIC reference.
