Non-parametric measurements performed in the Lyα images versus the ones performed in the rest-frame UV. From the upperleft to the lowerright: G^rP20, M20, C^minA, A, S, and SExtractor ellipticity (1 − B/A, where A and B are the semi-major and semi-minor axes of the detection ellipse). The dashed line indicates the 1:1 relation. The numbers reported in each panel correspond to the Spearman test coefficient, r, and probability, p, of uncorrelated datasets. r = 0 indicates no correlation, r = 1(−1) indicates direct(indirect) proportionality.
