Figure 2.
The image displays a histogram illustrating the distribution of porosity values represented on the horizontal axis ranging from 0.20 to 0.50. The vertical axis indicates probability density with values extending from 0 to 20. The bars of the histogram are shaded in light grey showing the frequency of porosity measurements with the tallest bar located around 0.30. Overlaying the histogram is a smooth red lognormal fit curve illustrating the distribution trend. A legend identifies the histogram and the lognormal fit curve. The overall layout assists in visually comparing the data distribution against the fitted model.Distribution of the porosity per voxel
