Data Release I of the Open Library of Magnetospheric Accretion Models for T Tauri stars, available through: https://github.com/marmicolta/database_magneto_models This repository contains the raw model data. For easy visualization of line profiles, exploration of the parameter space, and comparison with observations, we developed an interactive visualization tool: AREPAS (https://arepas.streamlit.app/) Details of the emission lines and parameter space available, and file name structure in the repo (https://github.com/marmicolta/database_magneto_models) Each file contains a line profile with: Flux per unit frequency (erg/s/cm^2/Hz) Velocity (km/s). Fluxes are calculated at the surface of each star (see Stellar Parameter table), i.e., to convert to luminosity (per unit frequency) multiply by 4πR*,mod^2
