Notes. ^(a) The integral flux above 400 GeV is calculated using the excess of events above an energy threshold, which differs slightly from the observed excess. The quoted error is statistical only and the 20% systematic error on the observed flux is not shown. ^(b) The percentage is calculated relative to the HESS Crab Nebula flux above 400 GeV (Aharonian et al. 2006a). ^(c) The , degrees of freedom (NDF), and corresponding  probability P() are given for fits of a constant to I(>400 GeV) binned nightly within a dark period, or monthly within a year, or yearly within the total. ^(d) The upper limit is calculated at a 99.9% confidence level (Feldman & Cousins 1998).
