Table 1: Mean proper motion and standard deviation of M 67 in several bins of magnitude in a circular field of $1^\circ$ radius resulting from the SEM deconvolution of field and cluster distributions. N is the number of stars per bin of magnitude, err $_{\mu _\alpha }$ and err $_{\mu _\delta }$ the median standard PM2000 errors, and P the proportion of cluster stars. The last line gives the statistics for Tycho2 proper motions for 36 members of the cluster.
