Table 1: Distribution of observations over the campaign.
Table 2: Logs of FU Ori observations.
Table 3: Averaged square visibilities for the 6 baselines.
Table 4: Model parameters for the small-scale structure. This best fit has a reduced $\chi ^2$ of 1.16 (with 306 individual measurements) and a "goodness of fit'' of 2%. The 3- $\sigma$ uncertainties on each parameter have been determined from a $\chi ^2$ map around the minimum, as shown in left part of Fig. 5.
Table 5: Model parameters for the large-scale structure without secular variation. The reduced $\chi ^2$ of the best fit is 0.95 (with 306 individual measurements) and the "goodness of fit'' is 70%.
Table 6: Parameters of the best model fit of the location of the spot in 1998, 1999, 2000, and 2003, and its quality.
