15″ × 15″ JHK finding chart for 2XMM J174016.0−290337. The large black circle is centred on the XMM-Newton position of 2XMM J174016.0−290337, with the radius indicating the 3″ positional error. The white circles represent the four candidate counterparts, hereafter referred to as sources 1, 2, 3 and 4 from left to right respectively. Sources 1 and 2 were classed as a single source in the UKIDSS-GPS DR3 database prompting the manual re-extraction of source astrometry and photometry.
