Goodness of the distortion solution (detector #2 H-band D15 data). Differences in arcsec between the relative positions of stars in the corrected HAWK-I frames and in the VVV reference image. Left panel X-axis and right panel Y -axis. The blue lines are Gaussian fits to the histograms. For both histograms, the centre of the fit lies at 0.0 arcsec, with σ = 0.04 arcsec.
