Left: PlanetFlow pipeline architecture. Dark blue boxes indicate required steps; gray boxes are optional. Dashed arrows denote optional execution paths, including the alternative input route from external stacking software (e.g., AS!4) directly into Step 03. Right: example output for Jupiter (2026 April 25, UTC+09:00), processed end-to-end with PlanetFlow. Rows correspond to three automatically selected time windows; columns show standard RGB, IR-luminance RGB (IR-RGB), and methane-band false color (CH4-G-R) composites.
