UBVI CCD Photometry of M11. II. New Photometry and surface density profiles Sung H., Bessell M.S., Lee H.-W., Kang Y.H., Lee S.-W. <Mon. Not. R. Astron. Soc. 310, 982 (1999)> =1999MNRAS.310..982S
ADC_Keywords: Clusters, open; HR diagrams; Photometry, UBVRI Keywords: stars: evolution - Hertzsprung-Russell (HR) diagram - stars: luminosity function, mass function - open clusters and associations: individual: M11 (NGC 6705) Description: This directory contains Johnson-Cousins UBVI photometric data for M11 (NGC 6705) and a neighboring field (around PN G027.4-03.5). The photometric data for M11 are tightly matched to the SAAO E-region standard system (Menzies et al. SAAO Circ., 1989SAAOC..13....1M; Menzies et al., 1991MNRAS.248..642M; Kilkenny et al., 1998MNRAS.294...93K). For the PN G027.4-03.5 region, the standard system of Landolt (1992, Cat. II/183) was used and small systematic difference in photometry between the two tables may be present, in particular in (U-B). Table 2 contains UBVI data for 14,179 stars brighter than V=17mag in M11 (about 40arcmin x 40arcmin region). The star numbers and proper motion memberships by McNamara et al. (1977A&AS...27..117M) and Su et al. (1998, Cat. J/A+AS/128/255) are also identified and included. Table 3 contains UBVI data for 3,676 stars around PN G027.4-03.5.
