Left: comparison between the v sin i derived from the fit of line profiles to a rotational profile, and v sin i derived using the FT technique. Centre: Comparison between the mean v sin i provided by GL05 and those measured in this work using the FT technique. Right: comparison between the mean v sin i provided by GL05 and those measured in this work by the fitting of line profiles to a rotational profile. The red dotted line shows the 1:1 relationship while the grey dashed line shows the best linear fit. The position of the Sun is shown with the symbol ⊙. Typical error bars in GL05 data are of the order of 1.4 km s−¹.
