ALMA supports a number of telescope pointing types or fieldpatterns. These pointings are specified in the Field Setup section ofa Science Goal, the Field Source section of an SB or in thecorresponding panel of the Spatial Editor of either.
In a Science Goal, the telescope pointing pattern is specified byselecting either Multiple single point fields or 1 rectangular field from the Target Type field. In an SB, thepointing positions can be chosen from a number of field patterns,including also including single point and rectangular fields. Whetheryou are editing a Science Goal or an SB, if the pointing position isrelative to the source position, moving the source position in theimage display will also change the pointing position.
The subsections below describe how to define the field centercoordinates of the pointings both for the single point andrectangular field options.
