Notes. Column (2) shows the morphological classification based on visual inspection. Galaxies that show tidal features are indicated with a ‘+’. We also show the BPT classification of the blueshifted and redshifted components in Cols. (3) and (4), respectively. In Col. (5), we show the total BPT classification using the non-parametric fit. In Col. (6), we indicate if we succeeded in performing a combined fit using a 1. We display the number of galaxies N_G associated in the same group in Col. (7) and the distance to the closest neighbour in Col. (8). We preferred to use Saulder et al. (2016), which is denoted with a † and, for galaxies at z > 0.11, we used Yang et al. (2007), denoted with a +. The denotations a, b, and c are the same as in Table 1.

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.
