Notes. The table details the changes in the weighted mean residuals of the identified and photometric SN Ia samples, as expected if resolutions in redshift and photometry were gradually improved w.r.t. their values in the present analysis (first line). All changes were estimated from synthetic SN Ia light curves. Uncertainties are statistical.
