Impact of K-corrections on t2(r) (top) and ℱr2 (bottom), as a function of redshift and x1 (left) and c (right). The colour of the data points represents the residual between the measured parameter in the SALT3 model at that point and the same model at z = 0. Overall, the impact of K-corrections is small, with a maximum residual on ℱr2 of 0.014 and on t2(r) of 0.66 d.
