Notes. Models used to represent the L-band data from MATISSE. The parameters are the PA of the major axis, the percentage model flux of the non-point source component (EX1), the percentage flux of the first point source (P1), and the percentage flux of the second point source (P2); x1, y1, x2, and y2 are the offsets of the point sources relative to the center of the FoV. The basic models are a point source (P), a uniform circular or elliptical disk (CD or ED, respectively), and a circular or elliptical Gaussian (CG or EG, respectively). In the case of Gaussians, size refers to the FWHM of the major axis, while for disks it is the angular diameter along the major axis. The stretch ratio is between that of the major and minor axis sizes. (a) The flux value was fixed from the start. (b)The parameters of the extended component were fixed after they were first obtained.
