The PSD for corner case 2. The solid blue curve is the sum of LDC waveforms INJ00520923 and INJ00520931. The waveform sum of the two catalogue UCBs in orange is a match with the sum of LDC waveforms. No other combination is a match. One can see from the red curve that there are high S/N UCBs on either side of the graphed waveforms. With the exception of INJ00520923 and INJ00520931, all injected waveforms have been recovered.
