J/A+A/388/149       CCD Vilnius photometry of M56           (Smriglio+, 2002)

CCD photometry in the Vilnius system in the vicinity of the globular cluster M 56. Smriglio F., Dasgupta A.K., Boyle R.P. <Astron. Astrophys. 388, 149 (2002)> =2002A&A...388..149S
ADC_Keywords: Clusters, globular ; Photometry, Vilnius ; Photometry, CCD Keywords: stars: fundamental parameters - stars: general - galaxy: globular clusters: individual: M 56 Abstract: CCD observations of field stars in an area north-east of the globular cluster M 56 were obtained in six bands of the Vilnius photometric system. The data sets cover a field of 9'x9.5'. An outline of the data pathway from observations to reduction via IRAF is outlined in this text. Photometry of 366 stars brighter than 18th V magnitude has been obtained and the analysis of the observational errors is discussed. Description: The observations using six Vilnius filters (P, X, Y, Z, V, S) were made on three nights in July 1995, October 1995 and July 1996 with the 1.52m telescope of the Osservatorio Astronomico di Bologna at Loiano (Italy).
