The gray histogram shows the distribution of the number of available fits in the SUPER catalog over available bands (left axis). The red or pink curves show the fraction of those fits obtained from either the SVI-multivariate normal (MVN) or MCMC method as functions of all 20 NIRCam medium or broad bands (right axis). Roughly 60% of these fits are retrieved from full MCMC sampling, which better characterizes the parameter posterior. The total number of available fits is around 10,000 to 20,000 in most of the deep broadband images. In ∼1 mag shallower mediumband images, the total number of successful fits drops to 4000 to 7000. Overall, 28,274 unique galaxies have acceptable fits in at least one band by either one of the pysersic methods.
