ΔAIC between base model (reference) and other models (see Table 3). Full and open blue markers correspond to models with and without redshift drift, respectively. Light markers show the results when the analysis is performed on the conservative sample rather than the fiducial one. Color bands illustrate the validity of the models, from acceptable (ΔAIC > −5) to excluded (ΔAIC < −20), see text. According to the AIC, all nondrifting models (open symbols) are excluded as a poorer representation of the data than the base (drifting) model.
