d_DLR distribution of the ‘normal’ SNe Ia are presented as a function of stellar galaxy masses, colour-mapped according to the global g − z rest-frame colours. Circles and squares represent NV and HV SNe Ia, respectively. Dashed horizontal line represent the separation of high mass and low mass galaxies at (log(M_⋆/M_⊙) = 10). There are eight NV SNe Ia with higher d_DLR values that are excluded from the plot to provide a clearer comparison between the two sub-types within the lower d_DLR ranges.
