Notes. Disk sizes correspond to Gaussian FWHM. In this work, these correspond to more than 50% of the peak in the reconstructed images. For (sub)millimeter and radio observations, these are estimates from deconvolved continuum images, while for Monnier et al. (2005) this is the diameter of a uniform ring. Column 3 describes the variability state of the Herbig star during each observation: outburst (O), quiescence (Q), and observed during both states (B).
