CCD photometry in the Vilnius system in the vicinity of the globular cluster M 56

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 $9\farcm\times9\farcm5$. An outline of the data pathway from observations to reduction via IRAF is outlined in this text. Ph...

Zusammenfassung: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 $9\farcm\times9\farcm5$. 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.
