Posterior widths for each property. The average ratio of the posterior standard deviation (obtained with 500 samples) and the prior standard deviation for parameters using a τ-delayed (top row) and Dirichlet (bottom row) prior for the SFHs. This is calculated across all the pixels for each of the 1.083 galaxies in the dataset, as a function of the average S/N in filters F277W, F356W, and F444W, at different redshift bins.
