Notes. The top rows show the results pertaining to the Tripp standardization, while the bottom rows show the results pertaining to the Tripp+δμD. In both cases, the same step locations obtained in Sect. 5.2.1 are used. ΔRMS is defined as the difference between the RMSsingle obtained when considering the Hubble residuals as a single population and the RMSdual obtained when considering them as two separate populations, each with a separate mean and divided at the step.
