Notes.

^(a)

Standard deviation of the log-normal portion of the N-PDFs.

^(b)

Slope of the power-law portion of the N-PDFs.

^(c)

Transition from log-normal to power-law portion of the N-PDFs in mean-normalized column densities.

^(d)

Slope of the exponential portion of the DGMFs.

^(e)

Slope of the power-law portion of the DGMFs.

^(f)

Relative errors of DGMFs account for 10%.
