Same as Fig. 2 but for the inner disc model. Top panels: CO(2-1) moment 1 (top left) and moment 2 maps (top right) computed from the data cube, after subtraction of the disc model (Section 3). A threshold of 3σ has been applied. The black cross gives the AGN position. Central panels: Moment 1 (central left) and moment 2 (central right) maps of the disc model of the inner r = 700 pc region. Bottom panels: Moment 1 (bottom left) and moment 2 (bottom right) maps of the residuals obtained by subtracting the model velocity and velocity dispersion maps (central panels) from the observed ones (top panels).
