Abstract: Wavelength calibration is a routine and critical part of any spectral workflow, but many astronomers still resort to matching detected peaks and emission lines by hand. We present RASCAL (RANSAC Assisted Spectral CALibration), a python library for automated wavelength calibration of astronomical spectrographs. RASCAL implements recent state–of–the–art methods for wavelength calibration and requires minimal input from a user. In this paper we discuss the implementation of the library and apply it to real–world calibration spectra.
