  The James Webb Space Telescope (JWST) near-infrared camera (NIRCam) has been
found to exhibit serious wisp-like structures in four of its eight
short-wavelength detectors. The exact structure and strength of these wisps is
highly variable with the position and orientation of JWST, so the use of static
templates is non-optimal. Here we investigate a dynamic strategy to mitigate
these wisps using long-wavelength reference images. Based on a suite of
experiments where we embed a worst-case scenario median-stacked wisp into
wisp-free images, we define suitable parameters for our wisp removal strategy.
Using this setup we re-process wisp-affected public Prime Extragalactic Areas
for Reionization and Lensing Science (PEARLS) data in the North Ecliptic Pole
Time Domain Field (NEP-TDF), resulting in significant visual improvement in our
detector frames and reduced noise in the final stacked images.
