Comparison between the data and the best-fit model for the SB1. From top to bottom, this figure shows velocity-integrated CO(3−2) flux density (Moment 0), velocity field (Moment 1), and velocity dispersion (Moment 2) maps for the data (left panel); the best-fit model (middle panel); and the residual after subtracting the model from the data (right panel). Gray-filled ellipses in the bottom-left corner indicate the angular resolution of 0.31″ × 0.25″. Each panel is 1.4″ × 1.4″, with the north being up and the east to the left.
