H-band Hubble diagram for the full sample with the a_H and R_H correction terms included. Panels c and d show the Hubble residuals when only a_H or R_H terms are applied vs. the quantity multiplied by the other, for example, in panel d the Hubble residuals vs. when only the a_H correction term is applied. Panels e and f show H and J band residuals vs. J_max − H_max color. In panel d the dashed lines are the extinction corrections for Milky Way extinction law with R_V = 1.7. The two red points surrounded by black circles are SN 2008bz and SNF20080512-008, which have been excluded from the fit (see text). The blue point surrounded a black triangle is PTF10hmv, which was observed only in H.
