Field-of-View Comparison

Roman WFI · SuperBIT · Euclid VIS · HST WFC3/IR · JWST NIRCam · Rubin LSSTCam — all co-pointed at the same field centre; the view auto-scales to whatever is toggled on

Roman WFI detector layout matches the official as-flown focal-plane geometry (precomputed and bundled as static data — no external requests). Other instrument footprints are simple rectangle/circle approximations of published FOV specs. HST/JWST are offset to the side purely for visibility, not to indicate relative sky position.
