Left: HST image of 3C 313 obtained with Wide Field Planetary Camera 2 with the wide filter F702W. The field of view is 2$\stackrel{″}{.}$5 × 2$\stackrel{″}{.}$5. The white plus sign marks the location of the radio core with its size showing the 0$\stackrel{″}{.}$18 uncertainty in the relative astrometry. Right: Chandra image at sub-pixel resolution filtered in the 2–7 keV energy band. We applied a Gaussian smoothing with two pixels in radius at one sigma. The images are oriented with north to the top and east to the left.
