(Top) Time-series white light curve capturing the transit of WASP-18b using the newly commissioned NIRISS SOSS multistripe subarray SUB680STRIPE_SOSS. (Bottom) Residuals compared to a best-fit light curve from juliet, using parameters from Deline et al., 2025. More sophisticated light curve fitting (e.g., including a Gaussian process), may improve the RMS scatter.

First Look at a Time-Series Observation with New NIRISS SOSS Multistripe Subarrays

[STScI] Beginning in Cycle 5, NIRISS SOSS enabled four new “multistripe” subarrays that facilitate faster readouts of the standard SUBSTRIP256 subarray footprint. At their limit, these subarrays enable unsaturated observations […]
