Azimuthally averaged radial intensity profile of the No-pileup model (left), Fiducial model (center), and Extreme model (right) observed at ALMA and ngVLA wavelengths. The radial bins are sampled at a width of 0.1 au. The error bar denotes the standard deviation of the intensities divided by the number of beam segments at each radial bin. The intensity is multiplied by a square of the wavelength to compensate for the spectral dependence of the blackbody radiation in the Rayleigh–Jeans limit.
