Posterior distribution for the free parameters in the fitting of the flux map. The dashed lines represent the 16th, 50th and 84th percentile. The galaxy is modeled as a 2D Sérsic profile, while the AGN is modeled as a two-dimensional Gaussian. The coordinates of the centers are expressed in arcseconds where the position (0,0) corresponds to the coordinates of RA = 03:32:29.3, Dec = -27:56:19.6. The radius of the galaxy and the standard deviation of the Gaussian component σ_x and σ_y are measured in arcseconds and θ_gal is the angle measured in radians between the y-axis and the semi-major axis of the galaxy.
