Contours showing the fraction of kilonovae detected as a function of start time and depth for observing Strategies 2 and 4 and all three filters when a pre-existing template is not available. We note an effect in z-band where the 95% contour drops by ∼1 mag for observations starting between 6 and 12 hr after the trigger using Strategy 2 and for observations starting less than 12 hr after the trigger using Strategy 4. This is the result of the observations straddling the peak of the light curve where the difference in flux between epochs is too small to detect.
