Follow-up Observations of JWST Pre-imaging

Same-cycle follow-up spectroscopic observations of sources identified through JWST NIRCam imaging programs are permitted. For example, a proposal may request imaging with NIRCam as a means of identifying a specific type of target (e.g. high redshift galaxies) for subsequent spectroscopy with NIRSpec. The proposal must include the imaging observation defined in APT, and specify the expected number density and magnitude distribution in the anticipated discovery of new targets. 

Proposers should be aware of the minimum timeline for pre-imaging, and other restrictions, detailed on NIRSpec MOS Operations - Pre-Imaging Using NIRCam.
