JWST Data Simulations and How to Use Them

The Near Infrared Imager and Slitless Spectrograph (NIRISS) is a contribution of the Canadian Space Agency to the James Webb Space Telescope (JWST). NIRISS is designed to perform:
a) low-resolution grism spectroscopy between 0.8 and 2.2 µm over the entire field of view;
b) medium-resolution grism spectroscopy between 0.6 and 2.8 µm, optimized for time-series observations of transiting exoplanets;
c) high angular resolution aperture masking interferometry between 2.8 and 4.8 µm; and
d) parallel imaging.
Accurate simulations of each observing mode are necessary to prepare for the NIRISS commissioning phase, validate the JWST calibration pipeline, and to confirm the scientific potential of NIRISS. In this poster, we present a summary of the tools developed by STScI to simulate JWST/NIRISS data and demonstrate how they can be used by the astronomical community to prepare for JWST observations.
