VizieR Online Data Catalog: Radial velocities of HD 166181 (Fekel+, 2005)
Abstract
In 1984 we obtained two spectrograms of HD166181 at the Kitt Peak National Observatory (KPNO) with the coude feed telescope, coude spectrograph, and a TI CCD detector. A hiatus of 10yr ensued before we resumed observations at KPNO in 1994 September. Through 2003 October we obtained an additional 58 spectrograms. All but two of the 60 KPNO spectrograms are centered in the red at 6430Å, cover a wavelength range of about 80Å, and have a resolution of 0.21Å. The remaining two are centered at 6700Å. The spectra have typical signal-to-noise (S/N) ratios of 150-200. All the KPNO velocities are listed in Table1.
>From 2003 May through October additional observations were acquired at the Dominion Astrophysical Observatory (DAO). Twelve radial velocities, listed in Table1, were obtained with the DAO 1.2m telescope, coude spectrograph, and radial velocity scanner. In addition to the above two data sets, three others are listed in Table1. Included are the five David Dunlap Observatory (DDO) velocities of Heard 1956PDDO....2..107H, the 18 Haute-Provence Observatory (OHP) velocities of Nadal et al. 1974A&A....37..191N, and the 13 KPNO velocities of Dempsey et al. 1996AJ....111.1356D.
