To characterize the performance of MAGIC under moonlight we used 174 hours of Crab Nebula observations taken between October 2013 and January 2016, under NSB conditions going from 1 (dark) up to 30 x NSBDark4.When dividing the data we aimed to have rather narrow NSB bins while keeping sufficient statistics in each of them (~ 10 hours per bin).Observations were carried out in the so-called wobble mode (Fomin et al., 1994), with a standard wobble offset of 0.4o.

To characterize the performance of MAGIC under moonlight we used 174 hours of Crab Nebula observations taken between October 2013 and January 2016, under NSB conditions going from 1 (dark) up to 30 × NSBDark4. Observations were carried out in the so-called wobble mode (Fomin et al., 1994), with a standard wobble offset of 0.4◦. All the data correspond to zenith angles between 5◦ and 50◦. For this study we selected samples that were recorded during clear nights, for which the application of the MC corrections described in (Fruck et al., 2013) are not required.
Data were divided into different samples according to their NSB level and the hardware settings in which observations were performed (nominal HV, reduced HV or UV-pass filters), as summarized in Table 1. When dividing the data we aimed to have rather narrow NSB bins while keeping sufficient statistics in each of them (∼ 10 hours per bin). Bins are slightly wider in the case of the UV-pass filter data to fulfill that requireme
