ATMOSPHERIX reads t.fits files from the Canada-France-Hawaii Telescope's near-infrared spectropolarimeter SPIRou, processes the data to remove telluric/stella contributions, and performs the correlation analysis for a given planet atmosphere template. The correlation function computes the correlation between the data and model for a grid of planet velocimetric semi-amplitude and systemic velocity. ATMOSPHERIX takes transmission spectroscopy into account and allows the user to inject a synthetic planet if desired.
