Details on Observing Strategy and Trigger Criteria
We request 2 TOO triggers, to observe two NS mergers discovered in
LIGO-Virgo run O4, satisfying any one of the following criterion: 1)
a BNS merger that is nearby (<~150 Mpc), 2) a BNS merger residing in a
relatively dense environment or 3) the first NS-BH with an electromagnetic
(EM) counterpart. The XMM-Newton observations would be triggered only if
an EM counterpart with ~arcminute or better localization exists. Based
on our simulations, we propose that the optimal strategy for each merger
is to carry out the first observation as rapidly as possible (<5 days
post-merger), and subsequent epochs at ~10--20 days, 1--3 months and 3--6
months. Accordingly, we request 4 epochs per trigger. For each trigger,
if no X-ray counterpart is detected in the first three epochs then we
will forgo the fourth epoch.
