Distance measures are important Figure of Merits to evaluate the detector sensitivity, the typical ones are: Horizon distance and Range distance.
In this study we extend Range distance from the single detector into the multi-detectors network. We also apply Range not only for the detection (SNR) but also for the sky localization confidence area (CA).
The original study on the single detector Range is at: https://arxiv.org/abs/1709.08079
