NGC4151
After processing the recently promoted dataset for the NGC4151 region with SPA-1-CMOS of 14APr2023, ir occurred to me to reprocess the SPA-2-CMOS dataset using the SPA-1-CMOS version as a reference for MultiscaleGradientCorrection. This dataset has gradient problems, and MGC suppressed them signifucantly.
