Derived calibrator parameters.

thumbnail Fig. 4

Similar to Fig. 3, but for the four other data sets with good uv-coverage. The log χ2 is shown as a function of Rosseland angular diameter and phase, of the same two model cycles as in Figs. 1 and 2. The phase of the data set is given in the upper right corner of the panel and is plotted as the horizontal dotted line. The vertical dotted line marks the photometric diameter. The intersection of the dotted lines shows where the minimum χ2 should be if the model is correct.
