Fig. 5
Coordinate differences with respect to first epochs as a function of time for a random SMC source. Contiguous lines represent the linear least squares fits through them and their slope corresponds to the proper motion in pix day-1 in the x and y directions. The rms of the fits is on average 0.12 pix and is indicated by dashed lines.
