exoatlas accesses, organizes, and visualizes populations of exoplanets and Solar System bodies. The toolkit retrieves and updates planetary data from online archives such as the NASA Exoplanet Archive and JPL Solar System Dynamics, organizing these data into population objects that provide convenient access to planetary and stellar properties. Built-in utilities compare planetary populations and generate visual summaries of their characteristics, enabling exploration of exoplanet datasets and comparative visualizations for research and education.

tellrv measures absolute radial velocities for low-resolution NIR spectra. It uses telluric features to provide absolute wavelength calibration, and then cross-correlates with a standard star. Observations of a standard star are included for convenience; the code also requires both the telluric and non-telluric-corrected spectra.
