+any variability above 2.2 𝜎. For the total data set of 1.8 h, 95% confidence level (C. L.) upper limits on the photon flux are derived using
 the method described by Rolke et al. (2005). The energy threshold
 of the data is highly dependent on the zenith angle of the observations. For these observations, the zenith angles range from 15 to 25
 deg, which leads to an energy threshold for the stacked data set of
