NIRCam primary dither pattern type. Possible values when NIRCam is the only operating instrument, or Imaging prime with MIRI Imaging, NIRCam Imaging, or NIRISS WFSS in parallel, are: FULL, FULLBOX, INTRAMODULE, INTRAMODULEBOX, INTRAMODULEX, INTRASCA, SUBARRAY_DITHER, NONE. When NIRCam Engineering Imaging is prime with FGS External Calibration in parallel, possible values are the same plus WFSC. When NIRCam WFSS is prime with either MIRI Imaging or NIRISS Imaging in parallel, the possible values are only: INTRAMODULE, INTRAMODULEBOX, INTRAMODULEX, NONE.
