Constraints on the calibration parameters.
|Fully Bayesian analysis||Local regression with SNIa|

Notes. Columns report the mean ⟨ x ⟩ and median values and the 68% and 95% confidence limits. The calibration procedure based on the local regression technique does not directly provi de the zero-point parameter b, which can be analytically evaluated as a function of (a,σint) by Eq. (27). The fully Bayesian analysis, furthermore, is related to a spatially flat model with dark energy parametrized through the CPL antsaz.
