NIRCam APT Templates

JWST NIRCam offers 5 observing modes, each with a corresponding APT template to design observations: imaging, coronagraphic imaging, time-series imaging, grism time series, and wide field slitless spectroscopy.

NIRCam has five observing modes.  Each has a corresponding template in the Astronomers Proposal Tool, APT. Each template offers different functionality and restrictions to guide users in designing their observations:
