Proper motion plot of point sources. Red crosses correspond to the RA/Dec motion of the point sources of the second epoch relative to the first epoch. The black line corresponds to the motion of a putative background star between the first and the second epochs. All motions of the point sources are compatible with the hypothesis of stationary background stars.
