WebRvidlines measures radial velocities from spectra by determining the wavelength shift in spectral lines relative to specified rest wavelengths. The basic usage consists of identifying one or more spectral lines (also called features), entering the rest wavelengths, and computing the average wavelength shift converted to a radial velocity.
