Comparison of N-PDFs. The blue histograms show the column density distributions of Maggie (middle panel) in comparison with the N-PDFs taken from a different GMF region analyzed in Syed et al. (2020) that trace the midplane H I emission (left) and CNM by means of H I self-absorption (right). The blue curve in each panel indicates a log-normal fit to the distribution. The red vertical dashed and solid lines mark the column density thresholds taken into account and the mean column density, respectively.
