Constraint Details
Monitor: Y
Criteria: We request to observe the source 10 times with cadence of once every 3 days, starting no later than MJD 59473. If possible, each 2ks observation should be observed with 5(4) consecutive orbits with 400s(500s) exposure. This makes it possible to sample the different phases of the QPO signal using NICER data. If this is not possible, then each observation should be scheduled at NICER's convenience.
