Performance Goals and Scheduling Constraints
The Performance Parameters panel defines the science performance required for this SB.
- Representative Target: A Phase-2 program needs a Representative Target in order to validate and generation will usually set this to the first Field Source. The Doppler settings will be set based on the Representative Target.
- Representative Coordinates: The coordinates of the Representative Target.
- Representative Frequency: The frequency to be used when determining whether the SB has achieved its sensitivity goal or not.
- Representative Receiver Band: Band corresponding to the Representative Frequency.
- Min. Angular Resolution: This gives the angular resolution of the nominal configuration (see below) minus 10 per cent. This field is not used at all during scheduling so changing its value has no effect whatsoever.
- Max. Angular Resolution: This gives the angular resolution of the nominal configuration (see below) plus 10 per cent. This field is not used at all during scheduling so changing its value has no effect whatsoever.
- Dynamic Range: Not currently used.
- Desired angular resolution: This is the value that was entered in the Science Goal.
- Largest Angular Scale: This is the value that was entered in the Science Goal.
- Nominal Configuration: This indicates that configuration that the OT decided was most appropriate to achieve the angular resolution and LAS. In practice, a different one might be observed.
