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 is made of stars
distributed over a circular area with radius of 22.8arcmin centered on
the cluster NGC 6611 (Kharchenko and Schilbach, 1995AN....316...91K 1995AN....316...91K).
To construct the compiled catalogue, we used also astrometric data
published by Van Schewick (1962VeUSB..62....1V 1962VeUSB..62....1V), Kamp
(1974A&AS...16....1K 1974A&AS...16....1K), Tucholke et al. (1986A&AS...66..311T 1986A&AS...66..311T), Bastian
and Roeser (1993, Cat. I/193), Roeser (1996, in "An updated GSC as
the astrometric reference for minor planet observations", Kluwer
Dordrecht, p. 481.), Hillenbrand et al. (1993, Cat. J/AJ/106/1906),
and photometry published by Walker (1961ApJ...133..438W 1961ApJ...133..438W), Hoag et al.
(1961PUSNO..17..343H 1961PUSNO..17..343H), Hiltner and Morgan (1969AJ.....74.1152H 1969AJ.....74.1152H), Sagar
and Joshi (1979Ap&SS..66....3S 1979Ap&SS..66....3S), The et al (1990A&AS...82..319T 1990A&AS...82..319T),
Hillenbrand et al. (1993, Cat. J/AJ/106/1906) as it described by
Belikov et al. (1998, A&A, in press, this paper, 1999A&AS..134..525B 1999A&AS..134..525B).
The catalogue contains 2185 stars up to the limiting magnitudes
V=16.78mag. It includes equatorial (equinox 2000.0 and epoch 1990.77)
and rectangular 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.
