Notes. For each indicator we list the value obtained using the Marino et al. (2013) method in Cols. 2 and 4 (M13), the Pettini & Pagel (2004) method in Cols. 3 and 5 (PP04), the R23 method (Pagel et al. 1979) for the upper limit in Col. 6 and the S23 indicator (Pérez-Montero & Díaz 2005) in Col. 7.
