Target Info

Target Name: 4U 1636-536
Target No.: 2030
Category: X-RAY BINARIES
Coordinates[J2000]: (250.23130, -53.75140)
Exp (ks): 14
Extended: N

Constraint Details

Monitor: Y

Criteria: Three 1-ks observations per week during the periods Feb 21 - Mar 6 and Mar 18 - Mar 31, 2020, or until the VLT has observed the target. This exposure is sufficient to collect enough counts to determine the source's state.

ToO: Y
Coordinate Observation: Y

Observatory: VERY LARGE TELESCOPE
Description: The VLT observations are dynamically scheduled. Therefore, we have a script that checks every minute whether the observation has started. Once it has, we will (via the same script) send an email to the NICER schedulers. The observations can be scheduled as closely in time as possible, although we note that strict simultaneity is not required for our science case.

Uninterrupted: N

Justification:

Estimated Count Rate (cts s-1): 200.000
