2 Observations

High resolution spectra of the programm stars were obtained with the 6 m and 1 m Telescopes at the Special Astrophysical Observatory (SAO) using the Nasmyth echelle spectrometer LYNX (Panchuk et al. 1993) and coude-echelle spectrometer CEGS (Musaev 1993) equipped with the $580 \times 530$ pixels CCD detectors. Table 1 provides a journal of all observations. Apparent magnitudes are from Hoffleit (1982).
