Beginning of ReadMe : II/130 2-D Classification, Vilnius Photometry M56 Region (Smriglio+ 1986) ================================================================================ Automated Two-Dimensional Classification from Multicolour Photometry in the Vilnius System Smriglio F., Boyle R.P., Straizys V., Janulis R., Nandy K., MacGillivray H.T., McLachlan A., Coluzzi R., and Segato C. <Astron. Astrophys. Suppl. Ser., 66, 181-190 (1986)> =1986A&AS...66..181S ================================================================================ ADC_Keywords: Photometry, classification ; Photometry, Vilnius Description: This catalogue gives the seven-color photometry in the Vilnius system stars and two-dimensional classification of 752 stars. Photographically determined magnitudes obtained by COSMOS (MacGillivray and Stobie 1984) on the Schmidt plates were input into software described by Smriglio et al. (1986) as a method of automated two-dimensional stellar classification in the Vilnius seven-color intermediate band photometric system (Straizys and Zdanavicius 1970). A region of approximately two square degrees in Lyra centered on RA(1950) = 19h14.6min, DE(1950) = 30deg05' in the direction of the globular cluster M56 was studied and the two-dimensional classification of 752 stars in the magnitude range V = 11 to 15 mag was studied. The photometric system, the method of reduction, the classification procedure and errors were described by Smriglio et al. (1986). The number of stars for which all the six color indices in the Vilnius system are available is close to 3000, but the number of stars which have received two dimensional classification is 752. The success rate of classification appears to be high for stars brighter than V = 15.0 mag for which photometric accuracy is better than +-5%.
