A.4 Visit Level Control

After an observation is completed, the FGS’s IFOV - under control of the 486 - is slewed to the expected location of the next target in the observing sequence. The search/track acquisition is initiated and the object, if acquired, is observed in either Position or Transfer mode. This process is repeated until all the exposures in the visit have been executed.
