Notes. WRMS is the error-weighted rms of prediction Hubble residuals (in magnitudes; see Appendix A); σpred is the intrinsic prediction error (in magnitudes); ρx1,c is the intrinsic correlation in prediction error with the standard (x1,c) predictors; last, Δx1,c is the difference in intrinsic prediction error with respect to (x1,c) (see Appendix B).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
