We present a model independent analysis of the Pantheon+ supernova sample and study the dependence of the recovered values of H₀, q₀ and j₀ on the redshift cut and on the modeling of peculiar velocities. In addition to the bulk velocity discussed previously, we also find a significant infall that we attribute to the presence of an overdensity out to a radius of R 120h⁻¹Mpc.
