Results of the MCMC retrievals of TiO features in the CARMENES spectrum of GJ 1002 using the narrow and wide spectral ranges and the unfiltered and broadband-filtered versions of the data. Each panel plots the results for a different parameter, which are grouped in columns. The first column contains panels for the fitted of the five TiO isotopologues. The second, third, and fourth columns contain panels for the derived isotope ratios relative to Ti, ⁴⁸Ti, and ⁴⁶Ti, respectively.In each panel, the mean parameter value from each MCMC fitting is indicated by a red marker while the 1σ and 3σ errors are indicated by black and gray bars, respectively. For the panels comparing abundance ratios, we indicate the corresponding terrestrial value with a vertical blue line.
