Corrections between UCAC3 and PPMXL

Differences between UCAC3 and PPMXL in positions and proper motions, on an all-sky one-degree grid. At each gridpoint we give the differences X(PPMXL)- X(UCAC3) averaged over all stars in a sqrt(2)/2-degrees environment around the gridpoint given. The corrections given here should bring UCAC3 based astrometry to the ICRS.
