Light curves of NGC 1275 between 2016 September and 2017 February in different energy bands. Upper panel: daily (black data points and blue upper limits) flux measurements above 100 GeV obtained from MAGIC observations. All flux upper limits are given at 95% confidence level and were calculated assuming a total systematic uncertainty of 30% using the Rolke et al. (2005) method. Middle panel: daily binned fluxes (black data points) calculated from Fermi-LAT observations in an energy range of 0.1–300.0 GeV. Flux upper limits were estimated at 95% confidence level in the case of TS < 25 and are shown in blue. Bottom panel: R-band flux density measurements by KVA are host galaxy subtracted and corrected for galactic extinction.
