NIRISS Observing Strategies

Recommendations are provided to guide users on choosing observing parameters, minimizing contamination, and designing efficient science proposals.

NIRISS has 4 observing modes:  imaging from 0.8 to 5.0 μm, wide field slitless spectroscopy (WFSS) from 0.8 to 2.2 μm, single object slitless spectroscopy (SOSS) from 0.6 to 2.8 μm which functions as the time-series observation (TSO) mode for NIRISS, and aperture masking interferometry (AMI) from 2.8 to 4.8 μm. 

Generic recommendations, as well as mode-specific recommendations, is given for choosing observing parameters and designing efficient science proposals in these articles:
