Comparison between ﹩v\sin {i}_{* }﹩ values from this work and those from the literature for the same star. The dotted line is a 1:1 relationship. Above about 6 km s−1, the agreement is good, but our ﹩v\sin {i}_{* }﹩ values derived through cross correlation with slowly rotating standard stars are generally overestimated for low projected rotational velocities. The bottom panel shows fractional residuals.
