Control
The
Control
panel provides the execution control limits for the OUS, in terms of items like the maximum time allowed, the user and TAC priorities etc.

-
Maximum Time
: This is the sum of allowed execution times for all parts of this OUS. It will accumulate the maximum times of all other OUSs and SBs below it in the hierarchy.
-
Execution Time
: This is the estimated actual execution time as calculated by the OT.
-
Array Type
: The array configuration to be used. Options are the 12-m Array, the ACA, the 7-m Array and the Total Power Array.
The following fields are currently not used:
-
User Priority
: This is assigned by the user to this OUS. It should perhaps be associated only with Scheduling Blocks rather than with (additionally) OUS, but applying to the latter might provide a convenience for recursion.
-
TAC Priority
: Priority of this observing unit as set by the TAC. Perhaps should only apply to SBs, but at the OUS level might provide a convenient mechanism for recursion.
-
Pointing Accuracy
: The desired pointing accuracy as the outcome of this calibration.
-
Bandpass Accuracy
: The bandpass calibration must be accurate to this level - deviation from the mean, expressed as a fraction.
-
Polarization Accuracy
: Polarisation must be calibrated to this level - probably expressed as a fraction.
