Notes. The first row corresponds to the 22-parameter fit of Rubin & Hayden (2016) with the full JLA covariances. In the second row, the peculiar velocity corrections they made are undone (and the corresponding arbitrary uncertainties imposed are excluded). The third row demonstrates the dramatic improvement in the fit when a scale-dependent exponentially falling dipole (with 2 additional parameters) is allowed for in q0.
