Proposed observing strategy and post-processing strategy for Roman Coronagraph operations. After the dark hole is created, high-order mode dithers are applied on the DM during the reference star observations and the corresponding science camera (EXCAM) images and low order wavefront sensor measurements are saved. After the science target observations, the science camera images are compared to the high-order mode dithered reference star image library using PCA-type algorithms to produce a custom speckle pattern that matches the science observations. This approach is a generalization of the tip-tilt and low-order mode dithers tested on JWST13 and Subaru11, 12 to high-order modes within a dark hole. In complement, the low-order wavefront sensor telemetry can be used to further inform the speckle pattern model by down-selecting or excluding specific images from the dither library depending on how they match with the science target telemetry.
