Premerger sky localization.

tpre 10 min 20 min 10 min 20 min

ET 63% 29% 68% 37%

ET+CE 5% 0.5% 5% 0.7%

ET+2CE 6% 0.5% 6% 0.6%

Notes. We show the fraction of BNS localized better than 100 deg2 at the merger that are localized better than 1000 deg2 at a premerger time tpre, for ET, ET+CE and ET+2CE. We show both cases that are detected with S/N> 8 and S/N> 7 at the premerger time. We consider only BNS observed at a viewing angle θv < 15°.
