Comparison of the best-fit parameters for the 3D model derived by 3D-Barolo fitting the approaching and receding side of the galaxy separately and simultaneously. From left to right and from top to bottom each panel shows vrot, σ0, vrad, ΣH I, i, and PA. The pink points refer to the best fit on the receding side, blue to the approaching side, and green to the simultaneous fit. The black horizontal dashed line in the vrad panel is a visual guide indicating the 0-level, whereas in the i panel is the indicative optical inclination angle from NED (de Blok et al. 2024).
