Notes. The center and the radius of each circular on-source (ON) region is given in Cols. 2–4. For Region A, the background was extracted from off-source (OFF) regions in the same field-of-view, while for Regions B and C, it was estimated from observations of separate OFF regions. Due to the smaller extent of Region A, more OFF regions could be used, which resulted in a smaller normalization factor α than for Regions B and C. The number of events in the ON and OFF integration regions, NON and NOFF, respectively, are given in Cols. 5 and 6. The significance (Col. 7) was calculated following the approach of Li & Ma (1983). The integral flux (or UL thereof) for each region is given in Col. 8. Note that the statistics presented here were obtained from a dataset comprised only of observations in 2007, which does not overlap with the one used in Aharonian et al. (2005a).
