Upper panel: asphericity of our large programme targets as a function of their volume equivalent radius. Both quantities appear highly correlated whereas the distribution of the asphericity as a function of target radius appears bimodal at first order (see Fig. 3). The correlation coefficient increases significantly when each subsample is considered separately. Lower panel: departure of the shape of our targets from their best-fit ellipsoid as a function of their volume equivalent radius. As in the case of the asphericity, both quantities appear highly correlated.
