A recovery test in F200W: the plotting convention follows Figure 4. In F200W, pysersic retrieves Sérsic parameters within fractional errors of 10% for the majority (68%) of the instances at a given magnitude or SNR, down to SNR ∼ 10. Similar to the recovery test in F444W, pysersic systematically underestimates the uncertainty for flux, half-light radius, and Sérsic index by a factor of roughly 2 (or 1.5, in the case of the Sérsic index).
