Fit to the CaT spectral region for a bin of approximately 9 arcsec roughly along the major axis of the centre of the NGC 448 field where the two distinct kinematic components have an absolute velocity difference of ∼212 km s⁻¹. The best-fitting model is in green. The contributions of the counter-rotating and main galaxy component are shown in blue and red, respectively. The green points signify the residual from our fitting and the orange line is set at the level of the resistant dispersion of the residual.
