Notes. The last two columns on the right give the intrinsic scatter of the calibration sample and the cosmological samples. The top part of the table shows the results obtained using the SBF calibration sample, and the bottom part the results obtained using the SH0ES calibration sample.
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.
