Notes. The results obtained with HEGRA (Aharonian et al. 2005) are also included for comparison. Columns denote from left to right: theregion of study (with coordinates and extension radius for the interaction regions) IACT instrument, effective exposure time, energy threshold for the UL calculation, and integral flux UL computed at 99% C.L.
