[ascl:2504.014] CHIMERA: CaltecH Inverse ModEling and Retrieval Algorithms
Line, M. R.; Lustig-Yaeger, J.; Batalha, N.; Marley, M.; Zhang, X.; Wolf, A.
CHIMERA (CaltecH Inverse ModEling and Retrieval Algorithms) retrieves exoplanet atmospheres, and can be used for both transmission and emission geometries with options for both the "free" and "chemically consistent" abundance retrievals. The code uses correlated-K opacities (R=100) with the random-overlap resort-rebin procedure and includes full multiple scattering in emission (both planetary and stellar reflected light) using a two stream approximation variant. CHIMERA includes multiple Bayesian samplers, including PyMultiNest (ascl:1606.005) and dynesty (ascl:1809.013).
[ascl:2503.017] IGRINS_transit: Cross-correlation detections of molecules in a transitting exoplanet atmosphere
Weiner Mansfield, Megan; Line, Michael R.
The IGRINS_transit data reduction pipeline takes high-resolution observations of transiting exoplanets with Gemini-S/IGRINS and produces cross-correlation detections of molecules in the exoplanet's atmosphere. IGRINS_transit removes low signal-to-noise orders, performs a secondary wavelength calibration, and uses a singular value decomposition (SVD) to separate out the signature of the transiting planet from the host star and telluric contamination.
