XRT 0.3–10 keV image of the region surrounding 1FHL J0644.2+6036 (black ellipse)/2FGL J0644.6+6034 (black-dashed ellipse)/3FGL J0644.6+6035 (black-dashed-dotted ellipse). Source #1 is the only XRT detection compatible with the 1FHL J0644.2+6036 positional uncertainty. Source #2 represents the counterpart to 2FGL J0644.6+6034 discussed by Massaro et al. (2013b) and Paggi et al. (2014). A third source located outside both Fermi error ellipses is neither numbered nor discussed in the text.
