J/A+A/451/901   Proper motion and BV photometry in Trumpler 2    (Frolov+, 2006)

Proper motions and CCD-photometry of stars in the region of the open cluster Trumpler 2. Frolov V.N., Ananjevskaja J.K., Jilinski E.G., Gorshanov D.L., Bronnikova N.M. <Astron. Astrophys. 451, 901 (2006)> =2006A&A...451..901F
ADC_Keywords: Clusters, open ; Photometry, photographic ; Proper motions Keywords: open clusters and associations: individual: Trumpler 2 Abstract: The results of a complex study of the galactic open cluster Trumpler 2 are presented. In order to obtain the proper motions, the positions of approximately 3000 stars up to the limit magnitude B∼16.25mag in the area 80'x80' around the cluster were measured on 6 plates with a maximal epoch difference of 63-years. The root-mean error of the relative proper motions is 4.2mas/yr. The catalogue of BV magnitudes of all the stars in the investigated area was compiled. The selection of the cluster members within the region of R<16 arcmin from the center of the cluster was made. Altogether, 148 stars were considered to be cluster members by both astrometrical and photometrical criteria. We present the estimated age (8.91E+07) and physical parameters of the cluster and append the catalogues of the proper motions and of the photometry of the stars. Description: All of the plates were scanned by means of the automated measuring complex "Fantasy" of the Pulkovo observatory. The description of the complex was presented in Frolov et al. (2002, Cat. J/A+A/396/125). File Summary:
