Fit success rate as a function of redshift and host mass. Top panels: Blue histogram shows the full ZTF Cosmo DR2 binned in redshift (left) and host mass (right). Orange histogram shows galaxies with isophote maps that pass all quality cuts. Green histogram shows final sample (successful galaxy fit + galaxy morphology identified). Centre panels: Success rate for generating a successful isophote map, given a galaxy image, as a function of redshift (left) and host mass (right). Bottom panels: Success rate for generating a galaxy model (successful galaxy fit + galaxy morphology identified), given an isophote map, as a function of redshift (left) and host mass (right).
