z=0 shows the SN template at B_max with features labels and
        normalized optical and NIR filters (U,B,V,R,I,J) over plotted to show which part of the
        spectrum is taken in to account when integrating with a filter
        and considering everything in the observer frame.

z=0.5-1.2 are done with the same SN templates and filters but the SN
                  data and the U,B,V filters have been red shifted to the
                  corresponding red shift while R, I, J filters are still
                  in the observer frame. The idea is to see which part of the
                  spectrum is observed in the case of high red shift SNe
                  when using R, I or J filter and to check at which rest frame filter
                  those correspond.
