Notes. For each photometric relation, we list the results obtained from the linear fits performed to the various galaxy subsamples in columns (all galaxies, spirals, S0s, Sa–Sab’s, Sb–Sbc’s, Sc–Scd’s, barred galaxies, and unbarred galaxies). The first row of results in each parameter (for each relation and galaxy subsample considered) corresponds to the fits performed to the data in the R band, while the second row corresponds to the results in the 3.6 μm band. In each linear fit, we provide the slope (m), the Y-intercept value (C0), the Pearson coefficient of linear correlation (ρ), the Spearman rank probability of random correlation (pS), and the number of data pairs available for each fit (see Sect. 3 for more details).

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.
