Predicted AB apparent magnitudes in the Gemini u, g, i, and K_s bands for an observer at a polar angle of 30 degrees and a distance of 40 Mpc. Comparison between a series of opacity models applied to the BLh profile. Left: Frequency- and composition-dependent opacities based on atomic calculations for neodymium and uranium (solid lines), versus the Just et al. (2022) prescription (dashed) and the simple Wu et al. (2022) opacity (dotted). Center: Opacities based on the neodymium atomic calculations, multigroup (solid lines) versus gray models (Rosseland or Planck, dashed and dotted). Right: Frequency-dependent LANL opacities including uranium (solid lines) or only neodymium (dashed) compared against the analytical Just et al. (2022) model (dotted).
