Scientific paper

We present results of our projected rotational velocities (Vsin(i))
measurements of F, G and K giants obtained from the cross-correlation function
(CCF) constructed from high signal to noise spectra. We also present the
calibration of the HET/HRS cross-correlation function to determine accurate
projected rotational velocities Vsin(i) for slowly-rotating F-K giants.
