Example of a pixel-by-pixel analysis of the Hα+[N II] flux derived from S-PLUS images using PELE and the Hα flux observed with MUSE for FCC 312. The lighter color (yellow) indicates a higher number of pixels, while the darker shade (purple) represents lower data density. The dashed red line is the 1-to-1 relation. The linear correlation diverges at ∼2×10⁻¹⁷ erg s⁻¹ cm⁻², marked by the solid blue line.
