Kernel-phase Detection Limits : Hypothesis Testing and the Example of JWST NIRISS Full Pupil Images
The authors derive hypothesis-testing based contrast detection limits for kernel-phase analysis and show JWST NIRISS full-pupil observations can detect companions at contrasts near 10^3 at 200 mas with controlled false alarms.
