Microturbulence distributions. Panels a and b: microturbulence maps at log τ = −5.0 for the IRIS and IRIS+ALMA fits, respectively; the contours are brightness temperature thresholds (5600 K – dotted, 5800 K – dash-dotted, and 6000 K – solid) of the average of the k2v and k2r peaks; the error bars in the color bar indicate the median and the range between the 16th and 84th percentiles. Panel c: corresponding (normalized) histograms.
