Log‐likelihood vs. dimensionless upper luminosity ν_u for models with a Λ^−1.8 luminosity function with a dynamic range of 10³. Results are shown for both the 64 ms (solid line) and 1024 ms (dashed line) data. (a) Results with ρ_c fixed to the best‐fit standard‐candle model values (ρ_c = 18.1 for 64 ms, 7.8 for 1024 ms). (b) Results with ρ_c slightly reduced (to 10 for the 64 ms data, and 5 for the 1024 ms data).
