Notes. The null hypothesis probed by the K-S test is that the Na I D EW of two samples divided according to a value between the 40% and 60% percentile of the galaxy property indicated in the leftmost column of Table 2 in Paper II comes from the same parent population. The K-S statistic, D, the p-value, the probability P of the p value being lower than 0.05, and the correlation rs are shown. Significant rejections of the hypothesis (PMCEW>50%Mathematical equation: $\mathbf{P}^{\mathrm{EW}}_{MC}>50\%$) are highlighted in bold.

Galaxy properties: T-type: Galaxy classification; ∆α: SN normalised offset; ∆αDLR: SN directional offset; ∆α(°): SN angular offset; i(°): Galaxy inclination; M*: Stellar mass; SFR: Star formation rate; sSFR: Specific SFR; Z*: Stellar metallicity; tage: Age; AV: Attenuation; n: dust index; τ: e-folding time.

*This probability is obtained from the median of 1000 bootstrap ’z-matched’ simulations on the two samples recalculating the K-S statistic at each iteration and additionally dividing the sample in two at 10 different positions around the median (40-60% percentile).

†The T-type samples are divided between spirals and ellipticals (at a fixed T-type = 0) instead of the range around the median (<T-type>~ 2).

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.
