RRT view should include t_0, not t_end
I noticed last night that the RRT view includes the t_end
value for the superevent. However, t_end
is not the time of the GW signal; it is the ending time of the superevent's time window, which is typically 1 second after the GW signal time (for CBC events). The RRT view should be changed to display t_0
(*) instead of t_end
. I will email Sushant to alert him to this directly; I can't seem to get his user ID to pop up here using @<name>
.
(*) In fact, t_0
is not guaranteed to be the time of the preferred event either, it seems; I think it is set for the first preferred event and not updated if some other event becomes the preferred event. I say this based on some recent examples on gracedb-playground: https://gracedb-playground.ligo.org/superevents/S230516ea/view/, https://gracedb-playground.ligo.org/superevents/S230516ep/view/ . But the time differences are typically at the milliseconds level, so t_0
should normally be good enough.
