Notes. Asymmetric (symmetric) profiles refer to cases with |RSk| – σRSk that are greater (less) than zero, respectively. Stars separated by subgroups as defined in Sect. 4.2.1 (see also Fig. 2). For reference, formally, a perfectly symmetric line implies RSk = 0, while positive (negative) values of the quantity RSk represent a redward (blueward) asymmetric line (see, e.g., panels A.3 and A.1 in Fig. 3, respectively).
