Comparison between the CRRL departure coefficients from Ponomarev & Sorochenko (1992) (panels (a) and (d); reproduced with permission from Ponomarev V.O. & Sorochenko R. L., 1992, Soviet Astronomy Letters, 18, 215. Copyright 1992, AIP Publishing LLC), this work using l-changing collision rates from Pengelly & Seaton (1964) (panels (b) and (e)), and those from Vrinceanu et al. (2012) (panels (c) and (f)) at T_e = 50 K. Lines marked as 1, 2, and 4 correspond to electron densities ﹩{n}_{e}=0.05﹩, 0.1, and 1.0 cm⁻³ (solid, dotted, and dashed lines), respectively. The top panels show b_n vs. n, and the bottom panels show the product ﹩{b}_{n}{\beta }_{n}﹩ vs. n.
