NIRCam operations are observatory-level capabilities applied for instrument science observations. These operations include pointing maneuvers such as dithers and mosaics. Dithers are performed between exposures to improve sky coverage and image quality. Mosaics are similar but are generally used to tile areas larger than the NIRCam field of view. All targeting is performed using apertures, which define each target's position and extent in the field of view.
Detector operations are covered in NIRCam Detector Overview.
