Notes. Column 1: the parameters estimated either directly or indirectly from the data. Columns 2, 3: the values estimated from the complete SN sample, both when allowing { ΩM,ΩΛ,H0 } to vary (All) and when imposing ΩM + ΩΛ = 1 (Flat). Columns 4–7: the values estimated from the subsampling of SNe into pixels of equal surface area, both when allowing { ΩM,ΩΛ,H0 } to vary (All) and when imposing ΩM + ΩΛ = 1 (Flat), before and after (Unbias) the implementation of the noise bias removal. For q0, the first row corresponds to the pixel averaging and the second row corresponds to the volume averaging. All the other parameters have one row corresponding to the pixel averaging.
