WebHL Tau has a circumstellar disk mass of 0.13 M sun, a characteristic radius of 79 AU, an inclination of 40°, and a position angle of 136°. Although a thin disk model is preferred by our two wavelength data sets, a thick disk model is needed to explain the high mid- and far-infrared emission of the HL Tau spectral energy distribution.
