The Sun & Dasgupta (2020) thermobarometer requires melt CO2 concentrations to be estimated. We currently include their option to estimate melt CO2 from observed SiO2 contents. Another option is to use Ba (e.g. https://doi.org/10.1016/j.epsl.2018.08.023). We could implement this/explore how the results compare.
