Flux density scale and astrometry checks, using the LoTSS DR2 image as a reference. There are 28 sources cross-matched between the LOFAR-VLBI corrected image and the reference LoTSS DR2 image. The large plot shows the integrated flux densities of these sources plotted against each other, with a line of equal flux density to guide the eye. The inset plot shows the astrometric precision. The histogram is the distribution of radial offsets of the difference in angular positions of the sources, in arcseconds. The grey line is a Rayleigh distribution with parameter s = 0.28′′ that describes the radial offsets well.
