Morpho-kinematic maps of the strong emission lines detected in the C component (z = 6.3425). Integrated intensities are given per spaxel. The corresponding maps of Hβ, [OIII]λλ4959, 5007, and [SII]λλ6716, 6731 are not presented due to low S/N. Due to the construction of our model, [NII]λ6548 has the same integrated velocity field, velocity dispersion map, and continuum map as [NII]λ6584, but an integrated intensity map that is a factor of 2.98 lower.
