For custom dither patterns, constraints on the dither step size are imposed by the WASP to ensure that the guide star remains within the guiding camera field of view. From the perspective of IFU users, careful consideration of the dithering options should be made. Below it's an example of custom dithering. Note that pointings are provided for each dither, rather than the dither pointings from an initial position. The three pointings provided in the example below would be executed as part of one only OB. Note that TARGID must be equal to TARGNAME in every row and that the . The maximum allowed distance between consecutive neighbouring dither points is 4 arcsec while the maximum overall dither distance across all dithers can exceed the maximum permitted dither 10.00 arcsec. Dither point positions cannot be repeated within an OB.
