Offset in RA and Dec of 61 sources crossmatched between the GMRT and LOFAR. The dashed line is the mean offset calculated from the original 92 sources, and the solid lines show the mean offset calculated after disregarding all sources more than five times their position error away from this mean in either RA or Dec. The final offset in RA and Dec was calculated to be 2.86 and 2.14 arcsec, respectively, and this correction was applied to the GMRT image.
