Calibrator Selection Tool
The tool allows the user to find calibrators based on various searchcriteria, including distance from a sky position and fluxdensity. This can only be used when constructing a Scheduling Block.

-
Cone Search RA
: The centre Right Ascension coordinate of the cone search.
-
Cone Search Dec
: The center Declination coordinate of the cone search.
-
Search Radius
: The search radius in degrees around the cone centre coordinates - 0.0 will use the whole sky.
-
Flux Min
: Minimum flux for the search.
-
Flux Max
: Maximum flux for the search.
-
Frequency Min
: Minimum frequency for the search.
-
Frequency Max
: Maximum frequency for the search.
-
Last Observed Min
: Minimum time since the last observation.
-
Last Observed Max
: Maximum time since the last observation.
-
Max Results
: Maximum number of sources to return (maximum 100).
-
Submit Query
: Find the calibrator using the given constraints.
-
Catalogue Selection
: Select either an internal or online catalogue.
-
Non-Sidereal Calibrators
: Display non-sidereal sources from the catalogue.
-
Select As...
: Use the selected calibrator for one or more calibration types (amplitude, phase, pointing, polarization, focus, or bandpass). The button will display a window to make the selection for calibration purpose and the spectral specification.
-
Close
: Close the tool.
