StellarSpectraObservationFitting.jl (SSOF, /suf/ like soufflé)

StellarSpectraObservationFitting (SSOF) is a Julia package for measuring radial velocities and creating data-driven models (with fast, physically-motivated Gaussian Process regularization) for the time-variable spectral features for both the telluric transmission and stellar spectrum measured by Extremely Precise Radial Velocity (EPRV) spectrographs (while accounting for the wavelength-dependent instrumental line-spread function)

This package is in rapid development so do not expect any stability yet, but the current version can be installed with the following

using Pkg
# Pkg.develop(;url = "")  # if you wanted to be able to locally edit the code easily
