Intensity and kinematic information extracted from the ionized gas with SITELLE SN3 data cube. Top panels: Ionized gas intensity (left) and the heliocentric velocity (right) corresponding to the main velocity component. The ionized gas intensity has a threshold of 6 × 10⁻¹⁸ erg cm⁻² s⁻¹ Å⁻¹. The dashed squares correspond to the field of view displayed in the bottom panels. Bottom panels: Flux ratio ϕ₂/ϕ₁ (left) and velocity difference V₂ − V₁ (right) for the second kinematic component with respect to the first one. The contours correspond to the intensity levels (1.8 × 10⁻¹⁷, 3.6 × 10⁻¹⁷ erg cm⁻² s⁻¹ Å⁻¹) of the flux map of the main component (top left). The black cross symbol representing the M31 optical center, 00h42m44.37s + 41d16m08.34 (Crane et al. 1992).
