Determination of v sin i with Fourier transform techniques
Abstract
In this paper, the use of Fourier transforms to derive stellar projected rotational velocity -- v sin i -- is described. The main advantages of the representation in the Fourier domain come from the frequency behavior of the rotational profile, easier to visualize and to work with than in the wavelength domain. Some examples are taken from the literature.
