Notes. Column 1 refers to the scaling factor of the dust, line and continuum optical depths relative to the standard model The average escape probabilities are calculated for: Col. 2, numerically exact; Col. 3, Eqs. (3) and (5) with α = 1.5 and Δ = 0; Col. 4, Eqs. (8) and (5) with α = 1.522 and Eq. (9); Col. 5, Eqs. (11) and (5) with α = 1.438 and Eq. (12). a (-b) stands for a × 10b.
