Observation positions corresponding to the 2006–2008 data set (magenta) and the 2019 dataset (green) at offsets of 0.7° and 1.6° from the pulsar respectively. The white dashed circle indicates the test On region with 1° radius around the pulsar, whilst the white dotted circle indicates the 3.2° radius region beyond which the background is normalised. Green and magenta circles indicate the radius around an observation position with the same offset as the pulsar. Counts map and contours are otherwise as in Fig. 2, left.
