2D T-Tauri disk models for CO isotopologue and N2H+ lines

Several grids of 2D physical-chemical models of T-Tauri protoplanetary disks that were presented as part of the AGE-PRO (V; Trapman et al. 2025c) and exoALMA (XIII; Trapman et al. 2025a) ALMA large programs to measure gas disk masses from CO isotopologue and N2H+ integrated line fluxes.

The csv files provide the DALI model parameters and matching line fluxes and measured disk sizes. The jupyter notebook describes how these model grids, in combination with the class_gridfit.py python module, can be used to fit observed line fluxes and determine gas disk masses.
