Extended Data Fig. 8: Corner plot of the retrieved parameters for HD 149026b’s atmosphere.
From: High atmospheric metal enrichment for a Saturn-mass planet

From left to right: the metallicity [M/H], the C/O ratio, the 5-parameter T-P profile model from ref. 22 (thermal opacity, visible to thermal opacity ratio of the first and second visible streams, percentage apportioned to the second visible stream, and effective albedo), and the dilution coefficient as described by ref. 23.
