LOS velocity distribution of the subsonic flows. Panel a: subsonic flow velocity distributions at magnetized pixels (M_S > 2σ as discussed in Sect. 2.3) with no supersonic downflows and the corresponding Gaussian fits. Panel b: subsonic flow velocity distributions only for those pixels where a supersonic downflow component coexists and the corresponding Gaussian fits. The numbers on the right in each panel represent the label of the data set given in Col. I of Table 1. The numbers on the left denote the mean and standard deviation of the velocity distributions, in km s⁻¹.
