Table C.1
Parameters relative to the frank fits at each wavelength.
| λ [mm] | α | wsmooth | B80 [kλ] | θ [arcsec] |
|---|---|---|---|---|
| 0.89 | 1.1 | 0.001 | 2600 | 0.08 |
| 1.3 | 1.3 | 0.001 | 2940 | 0.07 |
| 2.0 | 1.1 | 0.01 | 2580 | 0.08 |
| 3.0 | 1.2 | 0.1 | 2240 | 0.09 |
| 9.1* | 1.5 | 1.0 | 2180 | 0.09 |
| 30* | 1.05 | 0.001 | 620 | 0.33 |
Notes. α and wsmooth are the hyperparameters used for the retrieval of the brightness profiles with frank. The last two columns report the baseline up to which the model reproduces the visibilities within 20% (B80), and the corresponding spatial scale. The rows marked with a* symbol highlight the datasets that have been first corrected for a central compact emission.
