Similar to Fig. 5, but for the quiet Sun region as outlined in Fig. A.1 for three different test cases showing only the distributions obtained from the continuum maps. Thus the arrangement of the panels is as follows: top row: histograms of velocity as computed from the continuum maps for three different times applying a double Rayleigh component distribution fit, bottom panels: combination of Rayleigh and Gaussian distribution (all cases obtained from continuum maps).
