TriArc: Detecting trace gases in exoplanet atmospheres
TriArc (reTRIeval ARCturus) uses Bayesian statistics to determine the minimum abundance of an atmospheric species in a given model atmosphere (excluding the species of interest) and spectral noise profile. The code is configured for transmission spectroscopy and is built using the forward modeling capabilities of petitRADTRANS (ascl:2207.014); it also uses PandExo (ascl:1906.016). TriArc has been used to calculate prebiosignature detection thresholds for various potential JWST targets.
