Peak-normalised surface brightness profiles of the FRESCO stellar continuum and Hα stacks along with their PSF-convolved best-fit GALFIT models and PSFs accounting for pixels only within the vertical strip along the centre of the thumbnail (top row) or within the hourglass mask (middle row). Bottom row: Peak-normalised Hα equivalent width ([Hα/C]) profiles for both the stacks and PSF-convolved best-fit GALFIT models. [Hα/C] ≥1 and increases with increasing galactocentric radius, suggesting the inside-out growth via star formation of star-forming galaxies as early as z ∼ 5.3.
