Absolute proper motion and space motion of the globular cluster M15
We have separated cluster members and field stars for stars in a regionaround the globular cluster M15. The membership of ultraviolet brightstars of M15 is discussed. The absolute proper motion of M15 has beendetermined with respect to the PPM catalog. An extragalactic calibrationof the proper motions has been performed. The calibration was done bymeasurements of galaxies on the Palomar Sky Survey glass copies andplates from the Schmidt telescope of the Observatoire de la Cote d'Azur(CERGA). We compare the three different methods of establishing absoluteproper motion for the globular cluster M15. The orbital parameters ofM15 have been derived. As a by-product of our work, we obtained foreight stars of the HIPPARCOS input catalog absolute proper motions,which may be used for the calibration of the HIPPARCOS proper motionsystem.

An astrometric catalogue of stars in the region of M15
We present positions and proper motions with respect to the PPMcatalogue of 863 stars in a field of 8 deg x 6 deg centered on theglobular cluster M15. The catalogue is based on measurements of 136plates from the Carte du Ciel telescope of Bordeaux, the CERGA Schmidttelescope, and the double refractor of Bonn. The modal accuracy of theproper motions is +/- 0 arcsec 15/100 a.
