Parameters describing the size and colour distribution as a function of redshift and luminosity.

Parameter Prior Med. ± 1σ Description
μR, 0 U(0, 2) 1.212 ± 0.004 Mean log Re at z = 0.3 and log Lr = 11.3.
ζR U(−3, 3) −0.80 ± 0.05 Linear scaling of the average log Re with redshift.
βR U(−3, 3) 1.374 ± 0.017 Linear scaling of the average log Re with log Lr.
σR U(0, 1) 0.183 ± 0.003 Intrinsic scatter in log Re at fixed redshift and luminosity.
μC, 0 U(1, 3) 1.751 ± 0.001 Mean u − g colour at z = 0.3, log Lr = 11.3 and average size.
ζC U(−10, 10) −0.412 ± 0.015 Linear scaling of the average colour with redshift.
βC U(−3, 3) −0.009 ± 0.005 Linear scaling of the average colour with log Lr.
ξC U(−10, 10) −0.007 ± 0.006 Linear scaling of the average colour with excess size.
σC U(0, 1) 0.053 ± 0.001 Intrinsic scatter in colour at fixed redshift, luminosity and size.

Notes. The parameters are introduced in Eqs. (5)–(8). Column (2): priors on the parameters. Column (3): median and 68% credible region of the marginal posterior probability distribution of each parameter given the data.

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.
