Notes. The values refers to light curves with 4 min bins and respectively in three energy bands: >0.2 TeV, 0.2-0.5 TeV, 0.5-5.0 TeV. Since a significant fraction ( ${\approx}40\%$ ) of the points in the light curve of MJD 53945 in the energy band 0.5-5.0 TeV have a significance of less than 2 standard deviations, its $F_{\rm var}$ is not estimated.
