Top: (From left to right) fBm column density field, statistical distribution of the Orion B (red) and fBm (grey) column densities, and power spectrum of the fBm column density field. For illustrative purposes, the fBm distribution has been scaled to have the same mean and standard deviation as the log column density distribution of Orion B, before being exponentiated. Middle: (From left to right) modified fBm column density field resulting from the histogram matching procedure, statistical distribution of the Orion B (red) and modified fBm (dashed blue) column densities, and power spectrum of the fBm (grey) and modified fBm (dashed blue) column density fields. Bottom: (From left to right) modified fBm column density field resulting from the histogram matching procedure and the spatial filtering process, statistical distribution of the Orion B (red) and modified fBm (dashed blue) column densities, and power spectrum of the fBm (grey) and modified fBm (dashed blue) column density fields.
