Notes. The MJD of the first and last night of the observation in each epoch between 2005 and 2009, the live-time, the number of ON- and OFF-source events, the excess and its significance are reported. These events are obtained with standard cuts and for all the observation the normalization factor between the OFF and ON exposures is 12.6. The last three columns list the integral flux above 200 GeV, the χ2, number of degrees of freedom (ndf) and the χ2 probability P(χ2) for a constant fit to the light curves binned by night within each year (first five rows), or yearly (last row) within the total observing period.*Derived with loose cuts and with the spectral index fixed to the global value ΓVHE = 3.45.**Night-by-night and year-by-year light curves are derived with loose cuts.
