Sources selected for astrometric correction, totalling 231, are plotted as coloured dots on the image plane, with each imaging facet marked by blue polygons. The average of the dDEC values and their standard deviations are marked within each facet. If we subtract the astrometric offset derived for DEC in this work (1.9134) from the mean values of each facet, the mean values of each facet are well below 1.2′′, the resolution of our image.
