Target Info

Target Name: 4U 1210-64
Target No.:
Category: X-RAY BINARIES
Coordinates[J2000]: (183.31167, -64.87528)
Exp (ks): 14
Extended: N

Constraint Details

Monitor: Y
Criteria: We aim our NICER observations to span two 6.7 day binary orbits of 4U 1210-64 to search for cycle-to-cycle variations and to place the XMM+NuSTAR observations in context.
Phase Dependent: N
Epoch:
Period:
Min:
Max:
Remarks:
Specific Time: Y
Start: 2023-12-25 00:00 UTC
End: 2024-01-08 00:00 UTC
Remarks: The orbital period of 4U 1210-64 is 6.7 days so seven 2 ks observations spaced every other days will cover just over two orbital cycles.
ToO: Y
Coordinate Observation: PREFERRED
Observatory: NUSTAR AND XMM-NEWTON
Description: While XMM and NuSTAR will simultaneously observe 4U 1210-64 on Dec 30 (MJD 60308.2-60308.8), it is not fully necessary for NICER to overlap in time. This request will place our guaranteed observations in context along the binary orbit
Uninterrupted: N
Justification:
Estimated Count Rate (cts s-1): 40.000
