Notes. N1 and N2 refer to the number of parameters describing the supernova model (Eq. (3)), σ(zp) is the photometric calibration uncertainty for each band, σc is the scatter of light curve amplitude around the model, and σ(eM) is the prior applied to the evolution parameter eM defined in Eq. (5). zp denotes the (pivot) redshift which minimises the equation of state uncertainty, and this minimal uncertainty is labelled σ(wp)). The last column is the reciprocal of the area of the marginalised uncertainty ellipse (Δχ2 = 1) in the (w0,wa) plane (and also in the (wp,wa) plane, see Albrecht et al. 2006, p. 97).
