Notes. Column 1: the parameters estimated either directly or indirectly from the fit. Column 2: the values estimated from the complete SN sample. Columns 3–4: the values estimated from the subsampling of SNe into pixels of equal surface area, before and after the noise bias subtraction. Column 5: The averaging method.
