Korg: Fitting, Model Atmosphere Interpolation, and Brackett Lines

We describe several updates to Korg , a package for 1D LTE spectral synthesis of FGKM stars. Built-in functions to fit observed spectra via synthesis or equivalent widths make it easy to take advantage of Korg 's automatic differentiation. Comparison to a past analysis of 18 Sco shows that we o...
