Relative differences between the envelope and interior rotation rates for each of the stars in the analyzed sample. For KIC 005184732 the red shaded part of the posterior denotes the values where Ω_E is exceptionally high and so a likely alias of the real rotation rate (see Sect. 4.3). Solid and dashed black vertical lines denote the median (16th and 84th percentiles of the distributions); for KIC 005184732 they apply only to the dark shaded part of the posterior distribution.
