Apparent colors and velocity data are shown (red points), along with posterior inferences from the application of the linear model. The blue points are the marginal posterior means for each of the intrinsic colors of each SN Ia. The black solid line represents the conditional mean intrinsic color–velocity function using the posterior mean estimates of the hyperparameters . The black dashed lines indicate the residual intrinsic scatter about the mean relation.
