Context for the active region transect and spectral variability along the SUSI slit. Top left: SJI with the analyzed transect overplotted; colored markers indicate the locations used for the example spectra. Remaining top-row panels (left to right): slit–time diagrams for Fe II 327.7358 nm showing (i) intensity at a fixed wavelength sample near the atlas wavelength, (ii) fitted line-core intensity, and (iii) fitted line-core LOS velocity, displayed as an illustration of the LOS velocity amplitude. Bottom row: five example spectra at the marked locations, shown as relative intensity (arbitrary units) and lightly smoothed for readability (visualization only). Vertical lines indicate the analyzed spectral lines.
