Position-velocity (P-V, top) and position-velocity dispersion (P-σ, bottom) curves of the stellar component of NGC 1052 from MUSE data (Sect. 4.1). Both curves were obtained considering a pseudo-slit of 1″ in width aligned according to the major axis of the rotation (i.e. 112°, Table 4). Velocities are centred to the kinematic centre, and the radius is calculated as the distance from the photometric centre. In the top panel the blue and red symbols indicate the approaching (negative velocities) and receding sides (positive velocities) of the rotation, respectively. The green lines give the R_eff (219, i.e. 2.4 kpc, Table 1) and R_eff/8 (275, i.e. 303 pc, Sect. 4.1), as labelled at the top. The grey dashed lines show the zero points for position and velocity, as reference. The field of view of the MEGARA observations is indicated with orange dotted lines. The typical uncertainty (extracted from the uncertainties estimated with pPXF) on the velocity and velocity dispersion measurements are generally ≤12 km s⁻¹ and ≤14 km s⁻¹, respectively.
