Notes. The table details the effect of the cuts on the first three years of SNLS data: all detections (Col. 2), subsamples of events identified by spectroscopy as Type Ia and core-collapse SNe (Cols. 3 and 4). The last column indicates the efficiency of the cuts for bright SNe Ia, derived from synthetic SN Ia light curves at low magnitudes (m0i < 23).
