SN selection | 1483 | 246 | 42 | 0.97 |
Host redshift available | 1233 | 208 | 38 | 0.80 |
Light curve sampling | 1152 | 203 | 35 | 0.75 |
χ 2 | 951 | 186 | 22 | 0.68 |
X1 and colour | 596 | 176 | 7 | 0.67 |
g − i vs. g | 539 | 176 | 1∗ | 0.67 |
r − z vs. r | 490 | 175 | 1∗ | 0.67 |

Notes. The effect of the cuts is given for all detections (Col. 2), for the subsamples of events identified by spectroscopy as Type Ia and core-collapse SNe (Cols. 3 and 4), and for synthetic bright SNe Ia (m0i < 23) with well sampled light curves (Col. 5). The type of the event marked with an asterisk was revisited after this analysis (see Sect. 4.2).
