Comparison of absolute and relative abundances derived from each retrieval methodology, demonstrating the small impact the wavelength range and broadband filtering have on the results. For each stable titanium isotope ⁱTi, the retrieved of the corresponding isotopologue ⁱTiO is shown on the y-axis, while the x-axis shows the absolute deviation in the relative abundance ⁱTi/Ti compared tothe terrestrial value (vertical dotted line). The markers colored green, blue, black, orange, and red are used for ⁴⁶Ti, ⁴⁷Ti, ⁴⁸Ti, ⁴⁹Ti, and ⁵⁰Ti, respectively. The results for the narrow and unfiltered, narrow and filtered, wide and unfiltered, and wide and filtered spectra are denoted by the circular, square, triangular, and diamond markers, respectively. The 1σ errors, derived from the MCMC posteriors, are shown in gray.
