Left: original image (900 px× 1200 px area of a single NISP detector). Horizontal striping indicative of row-correlated noise is easily noticeable. Middle: noise model constructed spanning the image’s width to specifically target and quantify the noise pattern. Right: corrected frame where the row-correlated noise has been mitigated. This image demonstrates that the procedure effectively addresses the noise issue without substantially impacting the extended emission in the image. The residual image persistence caused by the NISP spectra generates an apparent column-correlated noise.
