Fig. 4: Identification of SLGW Host galaxy.
From: An interference-based method for the detection of strongly lensed gravitational waves

This figure displays the results of host galaxy identification. The x axis represents the logarithmic value of the time-delay area, where the time-delay ratio is within 1‰ agreement with those from SLGW. The y axis denotes the event index of the false GGSL. The vertical dashed grey line and the dark-grey circles represent the average areas for true host galaxies and false host galaxies, respectively. Both the light-grey-shaded region and the error bars of the dark-grey circles denote the 1σ confidence intervals.
