Same as Figure 15 but showing the decline time–﹩{m}_{z}^{\star }﹩ slice of the phase space. As in Figure 15, the contaminants are not clearly separated from the kilonovae population in ﹩{m}_{z}^{\star }.﹩ However, as in Figure 16, the long decline times can be used to distinguish kilonovae from the contaminant populations.
