Notes. Columns: (1) Model code as described in Sect. 2 of Eliche-Moral et al. (2012). (2, 3) Major and minor axial ratios of the bulges according to the Cox et al. (2006a) criterion (A>B>C). (4, 5) Major and minor axial ratios of the bulges, derived considering the Méndez-Abreu et al. (2010) criterion (A>B located in the equatorial plane and C perpendicular to it). (6) Bulge triaxiality. (7, 8) Intrinsic average ellipticity and Vrot,max/ ⟨ σ⟩ in the bulge according to the Kormendy & Illingworth (1983) method, corrected for the effects of numerical thickening (see Sect. 3.3.2). Errors in the values listed in Cols. 2–6 are ~10% of the estimated values on average.
