Fig. 3
Left: high-angular (18.̋2) resolution column density of RCW 79. The contour levels characterize the gas in the compressed layer (above Av ~ 10–11) and the gravitationally dominated gas (above Av ~ 20). Right: PDF of the column density map. The distribution is characterized by two lognormals (dark and light green) with similar widths of σ = 0.18), and a power-law tail with a least-squares fit in red. The slope s of the power-law tail is –2.46.
