Scientific paper

Precise v sin i values have been measured for more than 60 F and G dwarfs. Spanning the range of 5-80 km/s, they are primarily useful for calibrating cross correlations up to about 50 km/s. The present values are compared to older ones from photographic spectra and it is found that most of the older data are adequate but have fairly large errors. However, the rotational-velocity catalog of Uesugi and Fukuda (1982) is contaminated with erroneous data and is, therefore, suspect as a source of stellar rotational information.
