Effect of a finer sampling in streamline radii r0 on the calculated fractional H2 abundance xH2 = n(H2)/nH at the recollimation point (z/r = 20) of each streamline for our reference S0 model. We note the convergence to a limiting curve as the sampling is increased and the calculation of the self-shielding H2 column becomes more accurate.
