Control and Performance
This page is for specifying the basic scientific requirements of theproposal which are subsequently used to set the technical setup ofthe observations.

The Science Goal
Control and Performance Parameters
|
-
Representative Frequency
: The frequency to be used when considering the performance goals identified for this Science Goal. It can be set manually, but otherwise is set to the centre frequency of the first spectral window, or the average continuum frequency.
-
Antenna Beamsize (
/D)
: Display of the primary beam size for each antenna. This depends on the Representative Frequency. This field is for feedback only.
-
Extended Config: Max Baseline (L) and its Beamsize (
/L)
: The maximum baseline (400 m) and synthesised beam corresponding to the Early Science extended configuration. These fields are for feedback only.
-
Compact Config: Max Baseline (L) and its Beamsize (
/L)
: The maximum baseline (125 m) and synthesised beam corresponding to the Early Science compact configuration. These fields are for feedback only.
-
Desired Angular Resolution
: The desired angular resolution for this Science Goal, at the Representative Frequency specified. For Cycle 0, this should be set to the angular resolution of one of the two available configurations as given above.
-
Largest Angular Scale of Source
: The largest source structure it is desired to image at the Representative Frequency. Enter an angular size if the source is extended; otherwise choose ``Point Source''.
-
Desired Sensitivity per Pointing
: The sensitivity aim of this science goal, at the Representative Frequency. Note that this parameter will be updated if it is changed in the Sensitivity Calculator.
-
Bandwidth used for Sensitivity
: Specify the bandwidth that should be used with the specified sensitivity goal. The options are
Aggregate Bandwidth
(sum of the bandwidths of each spectral window),
LargestWindowBandwidth
,
FinestResolution
(the smallest channel separation in your spectral setup), or
User
(specify the desired bandwidth using
Frequency Width
).
-
Does your setup need more time than is indicated by the time estimate?
: If your Science Goal is likely to need more time than the OT's estimate, usually for (
) coverage reasons, please check
Yes
. This choice should be explained in your Technical Justification.
-
Is this observing time contrained?
Check box for time-constrained observations.
Yes
will enable fields for the start and end times in UTC (ISO format). A calendar tool is available for selecting the date.
Allowed Margin
gives the tolerance on the entered dates and times.
-
ACA Use
: The ACA is not available for Early Science.
