Comparison of the Hα+[N II] maps derived from S-PLUS data with the Hα maps obtained from F3D/MUSE for FCC 263 (top) and FCC 312 (bottom). The left panels display the Legacy Survey images (a combination of g, r, and z bands) at the same scale as the Hα+[N II] maps from S-PLUS (middle panels) and MUSE (right panels). The contours are based on the MUSE Hα map, corresponding to isophotes of 1×10⁻¹⁸ (blue), 1×10⁻¹⁷ (green) and 1×10⁻¹⁶ (magenta) erg s⁻¹ cm⁻². No internal dust correction was applied to any map.
