Description:
CCD observations of stars in the region of the globular cluster M15
have been used to obtain astrometric positions of 1092 stars in the
central part of the cluster within the FK5 system. The purpose of this
catalogue is to calibrate astrometrically CCD observations by means of
measuring the positions of stars in M15. The comparison with other
catalogues and with measurements of photographic plates of the central
part of M15 indicates a mean accuracy of about 50 to 70mas for each
star of our catalogue.
