J/A+AS/119/307      Position in M15 (Le Campion+, 1996)

M15, an astrometric standard for CDD observations. Le Campion J.-F., Colin J., Geffert M. <Astron. Astrophys. Suppl. Ser. 119, 307 (1996)> =1996A&AS..119..307L (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, globular ; Positional data Keywords: astrometry - globular clusters: M15 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.
