Accuracy of the absolute astrometric calibration of VICS82 relative to 2MASS for unsaturated point sources matched within 1″. Points show the relative offset in R.A. and decl. of point sources extracted from a full VICS82 tile compared to their counterpart in 2MASS. Contours visualize the density of points in a smoothed-kernel representation. The mean offset is consistent with zero, with the standard deviation in the distribution of offsets in each direction Δα ≈ 0.″18 and Δδ ≈ 0.″15. Note that the internal positional accuracy is much better than this, with a residual of 0.″1 at the 5σ limit of the survey and less than ﹩0\buildrel{\prime\prime}\over{.} 05﹩ at ﹩{K}_{{\rm{s}}}\lt 20﹩ mag (see Section 2.3).
