Notes. Each column shows information as follows: 1) galaxy designation; 2) effective radius in the r band; 3) and 4) linear model parameters and errors without DIG-dominated fibres with r-band effective radius normalisation; 5) and 6) linear model parameters and errors with all fibres with r-band effective radius normalisation. Columns 7), 8), 9) and 10) show the same parameters as the previous four columns but for Ks-band effective radius normalisation. Each linear model was fitted using a Bayesian MCMC routine.

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.
