Abstract:
    We present the first proper motion study of M10 (NGC 6254). Absolute
    proper motions of about 532 stars in the field of the globular cluster
    M10 were determined with respect to Hipparcos and ACT reference stars.

    In addition to photographic plates of Bonn and Shanghai also wide
    field CCD observations as second epoch plates were used. The wide
    field CCD observations show an accuracy comparable to that of the
    photographic plates. A good coincidence of the solutions based on
    reference stars from Hipparcos and from ACT was found. Our final
    proper motions allow a sufficient separation of cluster and field
    stars. Two population II Cepheids were confirmed to be members of M10.

    The absolute proper motion of M10 was determined and combined with its
    distance from the Sun and its radial velocity. The space motion and
    metallicity of M10 indicates the characteristics of a halo object with
    an orbit reaching to a maximal z-distance of less than 3kpc.

Description:
    The file table3.dat shows the entire proper motion data.
    Its structure is that of the published Table 3.
