Notes. As default, we use the full Pantheon sample, fit a flat ΛCDM model, and include the covariance of peculiar velocities via the matrix V as described in the text. The label ‘hostz’ refers to the sub-sample with redshift measurements from host spectra. ‘ve corrections’ means we applied corrections from Carrick et al. (2015). ‘curvature’ means we fit a non-flat ΛCDM model. ‘H0 fixed’ refers to assuming a value of H0 = 73.2 km s−1 Mpc−1 and fixing the solar motion to the value inferred from the CMB dipole. Finally, with ‘bulk motion’ we refer to the assumption of a bulk flow as inferred by Carrick et al. (2015).
