16″  ×  11″ cutout of the 2003 ACS image of 1E 1207.4−5209 obtained through the 814W filter. The Chandra position of the target, as computed using the ACIS and the HRC observations, is shown. The circles (062 radius) corresponds to the uncertainty of the CCO position computed from the error of the Chandra coordinates and the accuracy of the 2MASS absolute astrometry. North to the top, East to the left.
