Table 1: Fit results of our NPOI data to models of a uniform disc (UD) and a fully darkened (FDD) disc. The formal errors of the diameter values are $\sim$ 0.01 mas, additional calibration uncertainties are $\sim$ 0.06 mas, total errors thus $\sim$ 0.06 mas.
Table 2: Characteristics of the stars that were used as calibration stars for our VLTI/VINCI observations of $\gamma$ Sagittae. Listed are the spectral type, the K-band magnitude, the uniform-disc diameter and its error, and the effective temperature, all from Bordé et al. (2002; based on Cohen et al. 1999).
Table 3: Details of our VLTI/VINCI observations of $\gamma$ Sagittae (date and time of observation, spatial frequency, azimuth angle of the projected baseline (E of N)), together with the measured squared visibility amplitudes and their errors. The last column denotes the number of successfully processed interferograms for each series. The effective wavelength for our $\gamma$ Sagittae observations is $\sim$ 2.19 $\mu$ m. For each date of observation, we list the equivalent uniform disc (UD) diameter obtained from only the data of the specific night. Using all data together, we obtain an equivalent UD diameter of $\Theta _{\rm UD}=5.93$ $\pm$ 0.02 mas, or an equivalent FDD diameter of $\Theta _{\rm FDD}=6.69$ $\pm$ 0.02 mas.
