Table 3: Spectral types of the program stars from Wang & Hu (2000), from photometry in the Vilnius system by Kazlauskas & Jasevicius (1986) transformed by us into spectral types following Strayzis (1977), and from classification of our Echelle spectra against the Yamashita et al. (1977) reference spectral atlas. The last columns give the E_B-V (from Fitzgerald 1970 intrinsic colors) and the spectro-photometric distances for our spectral classification and the photometry in Table 1.
