A Simple Code for Rotational Broadening of Broad Wavelength Range High-Dispersion Spectra

Abstract In high dispersion spectra of rotating bodies such as stars and planets, the rotation contributes significantly to, sometimes dominates, line broadening. We present a simple method for rotationally broadening large wavelength ranges high-dispersion spectra. The is rapid scales linearly with length spectrum array. For ranges, much faster than popular convolution-based provide code implementation this in publicly accessible repository.
