Scientific paper

Table 1 contains the list of candidates observed at McDonald Observatory on the 2.7m Harlan J. Smith telescope and on the 9.2m Hobby-Eberly telescope (HET) between 1999 November and 2002 April. The 2.7m data were obtained using the cross-dispersed echelle spectrometer (Tull et al., 1995PASP..107..251T) at the coude f/32.5 focus with a resolving power of either 30000 or 60000. The detector was a Tektronix CCD with 24{mu}m2 pixels in a 2048x2048 format. For this setting, the spectral coverage was from 3800 to 8900{AA} with gaps between the orders beyond 5800{AA}. The HET data were taken with the Upgraded Fiber Optic Echelle spectrograph (Harlow et al., 1996AAS...189.4207H) at a resolving power of 11000 on a 1024x1024 CCD. The spectral coverage was from 4500 to 9000{AA} with gaps between the orders beyond 7300{AA}.
