We present a combined analysis of data samples recorded under different observational conditions, down to gamma-ray energies of 100 GeV. The flux was found to vary between 0.5 -- 2 Crab units (integrated above 200 GeV), considered a low state when compared to known data. Although the flux varied on a day-by-day basis, no short-term variability was observed, although there is some indication that not all nights are in an equally quiescent state.
