Notes. The models used to represent the data from the L, M, N H, and K bands, taken with MATISSE, GRAVITY, and MIRC-X. Parameters include: size (angular diameter or FWHM), the PA of the major axis, the stretch ratio, and the flux level. The models used are uniform circular or elliptical disk (CD or ED, respectively), a circular or elliptical Gaussian (CG or EG, respectively). The stretch ratio is between that of the major and minor axis size.^(a) Flux value was fixed from the start. The size measurements in the K band were obtained using GRAVITY observations only.
