Comparisons of FoV, angular resolution, and PSF properties. (a) Subaru/SC image of the galaxy cluster Abell 2744 with the JWST/NIRCam [20] and Kim TMS Type-I FoV footprints overlaid. Insets show the same region observed with Subaru/SC and JWST/NIRCam, as well as in a “denoised” JWST image reconstructed using an efficient-Transformer network [21], approximating a deeper observation. (b) PSFs for Subaru/SC and JWST/NIRCam at the same angular scale and in logarithmic intensity. (c) Whisker plot of PSF ellipticity e and position angle θ across a JWST/NIRCam mosaic. Whiskers derived from the “denoised” image, shifted by a few pixels for clarity, retain the same pattern as the original, indicating that the field-dependent PSF variations remain even after image denoising.
