2. Observations

The high dispersion spectra were obtained on the 182 cm telescope of Mount Ekar station of the Astronomical Observatory of Padova with an Echelle spectrograph and a 550550 pixel CCD detector. The spectra covered the range from 430 to 680 nm by a resolution of about 0.06 nm. The medium dispersion spectra were obtained on the 122 cm telescope of the Asiago Astrophysical Observatory of the University of Padova using a prismatic spectrograph Camera VI which covered the range from 380 to 830 nm changing the angle of the prism. A 512400 pixel CCD was used as detector. The spectral resolution was 0.5 nm at H, 1 nm at H, and 3 nm at H. Some additional medium dispersion spectra (resolution 0.6 nm) were taken with a Boller & Chivens spectrograph mounted on the 182 cm telescope.

The spectra were reduced in the standard ways using the NOAO IRAF package at the Asiago Observatory. The sensitivity of the spectrographs were corrected using spectra of spectrophotometric standard stars obtained in the same nights. Hiltner 102 was used for the reduction of the medium dispersion spectra and HD17520 was used for the high dispersion spectra. A journal of the observations is given in Table 1.
