Southern open star clusters VI. UBV-Hbeta photometry of 18 clusters from Centaurus to Sagittarius.
Abstract
The photoelectric photometry (summarized in table 19) reveals the reality of 14 clusters of which 2 were previously uncatalogued, 9 have spectral types earlier than B3 and 8 contain 10 supergiants. The distances range out to 2.3 kpc from the sun. One cluster coincides with a Cepheid variable. Key words: open star cluster - photoelectric photometry - galactic structure.
