Testing the dependence of the detection ratio for injected sinusoidal signals in the K2 data. Test signals #5 and #6 of Table 1 are used in the “systematics filtering first, frequency search thereafter” (tfa+dft) mode. The long period signal has a brief template range around N_TFA ~ 100 where the detection ratio is optimal. The detection rate for the short period signal also saturates around this value but unlike the long period signal it remains around the optimum rate also for rather high TFA template numbers.
