The extremely young open cluster NGC 6611: Compiled catalogue, absorption map and the HR diagram.


Abstract (from CDS):

A compiled catalogue of astrometric and photometric data for about 2200 stars down to V=16.8mag is presented. The stars are located in an area with a radius of 22.8 arcmin around the extremely young open cluster NGC 6611 with the cluster center at (α,δ)2000.0=18h18m40s,-13°47.1'. The catalogue is based on new reductions of positions, proper motions, and of photometric data that have been published in this region and includes, among others, Hipparcos, AC/GSC and Tautenburg Schmidt plate observations. For the membership determination, spatial and proper motion distributions of stars in the region were analysed. An extinction map of the area and the cluster color-magnitude diagram down to MV=+1mag were constructed. The distance of NGC 6611 was determined as 2.14±0.10kpc.
