All positional derived data are given in milliarcseconds [mas]. All ICRF positions are taken 
from \citet{cma}.
$\alpha*$ stands for $\alpha{\rm cos}~\delta$. Column~1: ICRF quasar identification; 
Col.~2: Modified Julian Date of the observation; Cols.~3 and~5: positional differences 
from the astrometric analysis of the observations made in the photometry mode, in the sense near-IR minus~ICRF, in right ascension and declination, respectively. Near-IR positions are taken as the mean of those 
obtained from the $J$, $H$, and $K_{\rm s}$~bands; 
Cols.~4 and~6: precisions of the observed near-IR positions of the ICRF~quasars, in 
right ascension and declination, respectively, as derived from the astrometric analysis of the 
observations made in the photometry mode. These precisions are the combined errors from each of the 
photometric filters; Cols.~7 and~8: standard deviations of the 
positional measurements in the $J$, $H$, and~$K_{\rm s}$~filters in right ascension and declination, respectively; Cols.~9 and~10: mean of the standard deviations, as obtained from each of the 
photometric filters, of the differences observed minus calculated to the reference (UCAC2) 
stars in the photometry mode at the epoch of the observations; Col.~11: number of reference (UCAC2) stars 
used in the astrometric analysis of the observations made in the photometry mode.
