Major-axis FWHM of Gaussian distribution (fitted from our best-fit HDUST model) as a function of the HDUST inclination angle. All the other HDUST parameters are fixed. Blue points correspond to the fit in Hα and red points in Brγ. The vertical dashed lines mark our values for inclination angle derived from the HDUST analysis, fitting the data in Hα (blue) and Brγ (red). Note that the equivalent Gaussian fits show a similar extension (2.45 mas, marked in horizontal dashed line) for these values of i.
