PDFs from a SILCC-Zoom simulation together with the observed Draco PDF. The blue line shows the total hydrogen N-PDF at the 1.5 Myr timestep of the HD MC1 simulation (Seifried et al. 2017), which includes the CNM and UNM; see Sect. 1. The black line is the observed N-PDF of Draco, the green line the H I-PDF of Draco obtained from EBHIS, and the dashed red curves are the log-normal fits of the observed N-PDF. See also Fig. B.1.
