Southern open star clusters 3 UBV-H beta photometry of 28 clusters between galactic longitudes 297 and 353 degree.
Abstract
The photoelectric photometry yields 22 certain clusters. The parameters of each cluster are summarized in Table 29. Seven clusters have spectral types earlier than B3: two of these fall in Becker and Fenkart's (1970) inner arm - II; the other five are located in the inner arm - I and yield no change in the structure obtained from previous studies of young open clusters. Suspected supergiants have been found in ten of the clusters. Key words: open star cluster - photoelectric photometry - galactic structure
