Field Center Coordinates
This panel is visible if Individual Pointing(s) has been selected in the Source panel. Up to 150 pointings can be defined per Science Goal, distributed between multiple sources.
- Custom Mosaic: If the pointings overlap and should be processed as a mosaic, select this option (set as default if individual pointing(s) is selected). Each pointing must be a maximum of one antenna beamsize away from its nearest neighbour.
- PointingPattern: Field centre in absolute or relative coordinates. Offsets are determined with respect to the source coordinate. Absolute coordinates have not been demonstrated to work and should not be used.
- Offset Unit: Select the units for the offset. This is selected by default and should not usually be changed.
- RA: Absolute coordinate of the centre of the pattern or the offset from the field centre in Right Ascension.
- DEC: Absolute coordinate of the centre of the pattern or the offset from the field centre in Declination.
