In the following we show the distribution of found and missed injections, and the accuracy with which we recover interesting parameters. For different quantities, we display the detected value compared to the injected one. We consider detected events from HL double coincidences, with a minimum combined SNR of 8.
You can find here the list of loudest missed injections, ordered by increasing decisive distance and ordered by decreasing expected combined SNR.

Found and missed injections


The following plots show the distributions of simulated events (injections) and detected events, with respect to several variables of interest. We consider detected events from HL double coincidences, with a minimum combined SNR of 8.

Fig 1b.1.1 : Found and missed injections as a function of time, chirp mass and total mass (vs injected snr and the decisive effective distance - the second higher effective distance), for double (in light blue) and triple (in dark blue) coincidences. The open dots show missed injections, and the red stars show missed injections that have triggered gating.

The open dots show missed injections, and the red stars show missed injections that have triggered gating.

The open dots show missed injections, and the red stars show missed injections that have triggered gating.
