Map of 1.5′′ × 1.5′′ area surrounding the position of IGR J17480. Left panel: VLT/NACO image (this work), with superimposed error circles drawn at 1σ and 3σ radii of the X-ray transient positions obtained from Chandra (dashed circles) and the Moon occultation method (solid circles). X-Ray transients positions are computed combining the errors given by the authors (0.04′′ for MO, 0.06′′ for Chandra) and the uncertainty on the astrometric fit (0.05′′). Central panel: VLT/MAD image. Right panel: HST/ACS image in the F606W filter. The three sources inside the error boxes are marked as well. Source #2, marked with a dot, is the candidate counterpart (see text).
