J/A+AS/134/525 NGC 6611 compiled catalog (Belikov+ 1999) ================================================================================ The extremely young open cluster NGC 6611. I. Compiled catalogue, absorption map and the HR diagram Belikov A.N., Kharchenko N.V., Piskunov A.E., Schilbach E. =1999A&AS..134..525B (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Clusters, open ; Combined data; Reddening ; HR diagrams ; Photometry, UBV ; Photometry, infrared Keywords: open clusters, HR diagram Description: This catalogue contains data on stars in sky area of the open cluster NGC 6611. The catalogue is based on a new reduction of positions, proper motions, and photometric data whenever published in this region and includes among others, Hipparcos, AC/GSC and Tautenburg Schmidt plate observations. The basis of compiled catalogue constitute stars distributed over a circular area with radius of 22.8arcmin centered at the cluster NGC 6611 (Kharchenko and Schilbach, 1995AN....316...91K). To construct the compiled catalogue, we used also astrometric data published by Van Schewick (1962VeUSB..62....1V), Kamp (1974A&AS...16....1K), Tucholke et al. (1986A&AS...66..311T), Bastian and Roeser (1993, Cat. ), Roeser (1996, in An updated GSC as the astrometric reference for minor planet observations, Kluwer Dordrecht, p. 481.), Hillenbrand et al. (1993, Cat. ), and photometry published by Walker (1961ApJ...133..438W), Hoag et al. (1961PUSNO..17..343H), Hiltner and Morgan (1969AJ.....74.1152H), Sagar and Joshi (1979Ap&SS..66....3S), The et al (1990A&AS...82..319T), Hillenbrand et al. (1993, Cat. ) as it described by Belikov et al. (1998, A&A, in press). The catalogue contains 2185 stars up to the limiting magnitudes V=16.78mag. It includes rectangular and equatorial (equinox 2000.0 and epoch 1964.05) coordinates, absolute proper motions with respect to the Hipparcos proper motion system, photometric data (results of UBV, HJK photometry and color-excess) and cluster membership probabilities. X - and Y - directions correspond to right ascension and declination directions. The rms errors of right ascension and declination are 0.008sec and 0.14arcsec, respectively. The individual rms errors of proper motions and V-magnitudes are given in the catalogue. The membership probabilities of the cluster stars belonging to the core and corona were determined using information both on spatial and proper motion distributions of stars in the field.
