Constraint Details

Monitor: Y
Criteria: In our proposal, we request to observe the source 12 times with cadence of once every week. But J1331-32 is discovered only 5days ago, and archival ROSAT data showed that the source count rate increased by a factor of 10 within 7days. We thus request to observe the source 12 times with cadence of one observation per day, with exposure of 3ks for each observation to study short-term variability.
