Notes. Columns 2–6 show settings used for parameters in Table 2, Cols. 7–10 show statistics including all targets, and Cols. 11–14 show statistics when excluding AGN-associated candidates. The phase estimates describe the fraction of the matched SNe Ia with a good peak phase estimate that were accepted by the channel either prior to light curve peak or prior to −10 days with respect to peak light.
