SAPHIRES: Stellar Analysis in Python for HIgh REsolution Spectroscopy

The SAPHIRES (Stellar Analysis in Python for HIgh REsolution Spectroscopy) suite contains functions for analyzing high-resolution stellar spectra. Though most of its functionality is aimed at deriving radial velocities (RVs), the suite also includes capabilities to measure projected rotational velocities (vsini) and determine spectroscopic flux ratios in double-lined binary systems (SB2s). These measurements are made primarily by computing spectral-line broadening functions. More traditional techniques such as Fourier cross-correlation, and two-dimensional cross-correlation (TODCOR) are also included.
