Examples of the N-PDFs of individual clouds. Those used in the analysis are shown in dark grey, and the column density mapused is noted in the legend: N for NICEST (all of these). The blue, red, and yellow lines show the fits of PL, LN, and LN+PL models, respectively. The transition point of the LN+PL model is shown with a vertical dotted yellow line. All fits were performed above the extinction at the last closed contour, which is marked with the vertical grey line. The residuals of the fitted models are shown below the N-PDFs, and the best-fit model is noted in the legend.
