Photometric and Kinematic Studies of open star clusters. III. NGC 4103, NGC 5281, and NGC 4755 (kappa Cru) Sanner J., Brunzendorf J., Will J.-M., Geffert M. <Astron. Astrophys. 369, 511 (2001)> =2001A&A...369..511S
ADC_Keywords: Clusters, open ; Photometry, CCD ; Proper motions Keywords: open clusters and associations: general - astrometry - stars: kinematics - Hertzsprung-Russell and C-M diagrams - stars: luminosity function, mass function Description: Tables 5, 7, and 8 contain the data of the CCD photometry of the three open star clusters. We added the numbering systems of previously published papers to the tables. Table 5 contains the data of NGC 4103 with stellar numbers from Wesselink (1969MNRAS.146..329W); Table 7 the data of NGC 5281 with the numbers of Moffat & Vogt (1973A&AS...10..135M); Table 8 the data of NGC 4755 with the numbering system according to Arp & van Sant (1958AJ.....63..341A). In Tables 12, 13, and 14 we present relative proper motions of the three clusters (in the same sequence). For NGC 4103 the table contains the information of an entire Carte du Ciel field of 2 degrees square, for the other two clusters, a small subfield had to be selected beforehand. The numbers of Arp & van Sant (1958AJ.....63..341A) are encrypted in the following way: Numbers <100 stand for the stars A to Q, the first digit of the numbers >100 represents the quadrant. The two final digits are the running numbers in the notation of Arp & van Sant (1958AJ.....63..341A). File Summary:

Global notes: Note (G1): Notations: Arp & van Sant, 1958AJ.....63..341A, NGC 5286 NNN in simbad Moffat & Vogt, 1973A&AS...10..135M, NGC 5281 NNN in Simbad Wesselink, 1969MNRAS.146..329W, NGC 4103 NNN in Simbad Note (G2): For NGC 4103 and 5281, north is at the bottom and east to the right, for NGC 4755 north is to the right, east up. These are the "original" pixel coordinates as determined from the CCD images by DAOPHOT, therefore the strange orientation. (0,0) is the lower left pixel of the field which is centered on the cluster. For NGC 4103, three different fields were observed, for the other clusters two fields each. The coordinates of the other field(s) were shifted according to their location. The scale is 0.375 arcsec/pix (NGC 4103, NGC 5281) and 0.3 arcsec/pix (NGC 4755), respectively.
