CCD UBVRI photometry of NGC 6811
Original language description
We present the results of CCD UBVRI observations of the open cluster NGC 6811 obtained on 18th July 2012 with the 1 m telescope at the TUBITAK National Observatory (TUG). Using these photometric results, we determine the structural and astrophysical parameters of the cluster. The mean photometric uncertainties are better than 0.02 mag in the V magnitude and B - V, V - R, and V - I colour indices to about 0.03 mag for U - B among stars brighter than magnitude V = 18. Cluster member stars were separated from the field stars using the Galaxia model of Sharma et al. (2011) together with other techniques. The core radius of the cluster is found to be r(c) = 3.60 arcmin. The astrophysical parameters were determined simultaneously via Bayesian statistics using the colour-magnitude diagrams V versus B - V, V versus V - I, V versus V - R, and V versus R - I of the cluster. The resulting most likely parameters were further confirmed using independent methods, removing any possible degeneracies.
