SED of V892 Tau measured from ALMA and VLA observations. The fluxes of the inner and outer discs are represented by the blue and green points, respectively. Our best-fit power-laws and their corresponding spectral index are represented by plain orange lines between 0.9 mm and 3.0 mm (i.e. 100-333 GHz), and in black between 3.0 mm and 9.8 mm (i.e. 30.5-100 GHz). α_in and α_out are the spectral indices of the inner and outer discs, respectively. The error bars for the outer disc are smaller than the markers at wavelengths shorter than 3.0 mm.
