Convergence of the TRGB estimates in the RP band. The blue curve shows the cumulative mean TRGB absolute magnitude as a function of the number of sample draws. The red dashed line marks the final mean of the full sample. The dotted green lines indicate the final mean ±ϵ, with ϵ = 0.001 mag, and the black vertical line marks the convergence index k_conv. As discussed in the text, the sample draws were randomly reordered; therefore, the exact shape of the curve may vary between permutations.
