Refined XMM position (1.5′′ at 68% c.l.) of the source reported in the present work is compatible with the Chandra position of the faint source detected by Ratti et al. (0.6′′ at 90% c.l.; 2010) and is suggested to be the quiescent counterpart to XTE J1743-363. We also show the INTEGRAL position (0.7′ at 90% c.l.; Bird et al. 2010) and the Swift /XRT position (2.3′′ at 90% c.l.; see Sect. 3).
