III/253             MK Classification in NGC 2175         (Hovhannesian+ 2007)

Two-dimensional spectral classification of stars in the direction of the open stellar cluster NGC 2175 Hovhannesian R.Kh., Epremian R.A., Metrevelii M.D. <Astrofizika 51, 339 (2008)> =2008Ap.....51..276H
ADC_Keywords: Clusters, open ; MK spectral classification Keywords: Description: The results of the spectral classification of 1224 O-M stars of different luminosity classes in the region of NGC 2175 and around it are presented. The classification has been carried out on the basis of low dispersion objective prism spectra. Using the B-V and U-B data for 106 stars out of 1224 the MK classification has been done with the photometric Q-method.
