Significance and excluded significance maps. Left panel: VHE significance map displaying PSR B1259–63/LS 2883 (here labelled as HESS J1302–638) and the surrounding region. PSR B1259–63/LS 2883 itself is the central object in the image, where also of note is the nearby pulsar wind nebula HESS J1303–631 (Aharonian et al. 2005a) directly to the north (see text for further details on this source). Also shown in blue in the lower left of the image, is the 68% c.i of the point spread function for these observations. Right panel: the significance map of PSR B1259–63/LS 2883 and its surrounding region after masking the two sources. The bins in both maps are correlated within a circle of radius 0.1°.
