Figure 2:
Synthetic squared visibility function
for (dashed line) a 5 mas Gaussian,
(dashed-dotted line) a 30 mas Gaussian,
and (solid lines) two examples for a two-component model
where (upper line/ lower line) 56%/40% of the total flux comes
from a 3 mas/0.1 mas Gaussian and the
remaining 44%/60% from a 54 mas/42 mas Gaussian ( FWHM values).
Measurements are available for baselines B=46 m reported in this
letter (marked by the -symbol with error bar)
and up to B=6-10 m
(Wittkowski et al. 1998; Weinberger et al. 1999;
Weigelt et al. 2004).
Both measurements are only matched if the small component has a size
clearly below 5 mas and if only part of the total flux in our FOV
arises from this
5 mas component, and another part from a
larger component.
It is assumed that the FOV is the same for all shown models. |
