Effect of the SN Ia selection cuts.

Cut Events Ia CC ϵ(Ia)

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
i − z vs. z 485 175 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).
