Observations and data reduction

The observations were carried out with the 6m telescope of the Special Astrophysical Observatory of Russian Academy of Sciences (SAO RAS) in the period from December 1992 to October 1996. Medium resolution spectrograph SP-124 in the Nasmyth-1 focus was used over the whole period with two different modes of registration. For the period prior to December 1995 the spectra were obtained in the IPCS mode (see the description of IPCS in Drabek et al. [1986]; Afanasiev et al. [1986]). Since January 1996 we used for registration Tektronix CCD 1024$\times$1024 provided by Astrophysical Institute Potsdam (AIP, Germany) in the frame of mutual cooperation between AIP and SAO RAS.
