True detection rates for dataset H0+T0-a using various signal search methods (BLS0, BLS1, and BLS3 with respective detection rates of DR0, DR1, and DR3). Upper and lower panels: results obtained with zero and 1 yr gap between H0 and T0. The FARs used to correct the observed detection rates are displayed in the insets. For gapped data, the FAR increases considerably, leading to a decrease in the true detection rates.
