Wavelength-size relation for model 24 oriented at various position angles with respect to the NE direction. The colored lines correspond to various position angles of the black hole spin on the sky, ξ. Size for λ> 13 mm are not modeled because they fall outside our simulation domain. All observational data taken from Bower et al., except one point at 1.3 mm which is taken from Doeleman et al. (2008), which is a fit to the symmetric Gaussian function (due to a poor uv coverage at 1.3 mm). At 1.3 mm the average of major and minor axis of the source are in agreement with the measured size. Horizontal dashed line corresponds to FWHM_maj = 1.309λ².
