Flux maps for the blue-shifted and red-shifted velocities from the multi-Gaussian fitting. We select the region [−2200, −250] km s⁻¹ to extract the flux map for negative velocities (the left panel). In the right panel, the flux map for the positive velocities [250, 2000] km s⁻¹. The light blue, yellow, and green contours indicate the 4, 3, and 2σ levels, respectively. These contours help to determine the significance level of the measured flux values. The blue dashed line represents the maximum distance to the 3σ fitted ellipse in white.
