Runs and variants
Is the preference for evolving dark energy spread across the supernova data or concentrated in one redshift range?
Excluding z = 0.01–0.15 from DES-SN5YR reduced the fit improvement by about 75%, the largest reduction in this comparison. The ranges had unequal influence, without establishing exclusive dependence on any one of them.
