Spatial distribution of positional offsets uncorrected (left panels) and corrected (right panels) between high S/N and compact LOFAR sources and their FIRST counterparts in the right ascention (top panels) and declination (bottom panels) directions. The colorbar denotes the offsets for each object. We find 989 LOFAR/FIRST sources (left panels) using the uncorrected positions; when the astrometry corrections are applied a total of 1048 LOFAR/FIRST sources are found (right panels). The black circle indicates the radial cutoff used to apply the primary beam correction, while the green lines show the facet distribution in our Boötes mosaic.
