Beginning in Cycle 5, the NIRISS SOSS instrument will be offering several new “multistripe” subarrays, which offer a greatly improved bright limit compared to the existing standard subarrays, while simultaneously retaining the full SOSS wavelength coverage of 0.6 to 2.7 micron. These subarrays have been designed such that all known exoplanet transit hosts can be observed without saturation. In this JWebbinar we will present:

• An introduction to multistripe readout, and its application to the new SOSS subarrays.
• A breakdown of the relative tradeoffs between the multistripe subarrays and the standard SOSS subarrays.
• A short walkthrough of the SOSS multistripe in the JWST ETC and APT.
