Fig. 1


Properties of our sample of galaxies. The panels show the normalized histograms of morphological T types (a), optical radii R25 in kpc (b), optical radii R25 in arcmin (c), distances to the galaxies in Mpc (d), galaxy inclination angles (e), central (intersect) oxygen abundances 12 + log(O/H)0 (f), radial oxygen abundance gradients in dex (g), scatter in oxygen abundances around the linear O/H – Rg relation (h), and number of points in the abundance map of a given galaxy (i).

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.
