Results of the inference of the tangential component of macro-turbulence. Top panel: Histogram of a_T contributions derived from observed profiles of the entire sample with a_T = 0.5 as an initial assumption, ν sin i varied within errors of ν sin i_FT. Middle panel: Histograms of α_T contributions derived from observed profiles of the entire sample with different initial assumptions: 0.25 (yellow), 0.5 (blue), 0.75 (green), and ν sin i left to vary freely. Bottom panel: KDE functions for the same data as in the middle panel. Dashed lines mark initial guesses. The fits demonstrate the results are sensitive to the initial guess.
