Notes. 

(a)

The dynamically “young” and “old” classification as discussed in Sect. 4.1 and in Bitsakis et al. (2010).

(b)

The original classifications of HCG4 and HCG71 were dynamically “old”, but changed as explained in Sect. 4.3.

(c)

The classification to Phases 1, 2, and 3, follows the definition of Verdes-Montenegro et al. (2001).

(d)

The upper and lower limits, in HI masses, taken into account by means of survival analysis.

(e)

The H2 masses were obtained from Martinez-Badenes et al. (2011).

(f)

Ratio of the total baryonic mass Mbar = Mstar + MHI + MH2 over the dynamical mass Mdyn.

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.
