Significance map of the region around PSR B1259–63/LS 2883 (white cross) obtained from the analysis of the 2014 data set in CT1–5 stereo mode. The pulsar wind nebula HESS J1303–631 (best-fit ellipse centre (Aharonian et al. 2005c) indicated by a grey dot) is also detected to the north of PSR B1259–63/LS 2883. The bins in the map are correlated within a circle of radius 0.14°. Significance contours are shown at the 5, 10, and 15σ levels. Some artefacts in the map are visible, occasionally exceeding the 5σ level, and are discussed in the text (see Sect. 4.1). In the inset, the point-spread function of the analysis is shown together with the respective contour lines.
