Predictions of Network I at 230 GHz. The predictions of the 10 000 points in the validation set of network I at a frequency of 230 GHz with various amounts of Gaussian beam widths. The color coding is based on the deviation of the network prediction with respect to the true value, weighed by the network uncertainty. The red points indicate predictions that are correct within three or more σ. The units of the viewing angle and PA are degrees (°) of the mass accretion rate solar masses per year (M_⊙ yr⁻¹) and the mass is expressed in solar masses (M_⊙). Left to right: no Gaussian beam and Gaussian beam widths of 5, 10, and 20 μas. Top to bottom: viewing angle, mass accretion rate, R_high, mass, and PA. The sawtooth pattern in the PA at large Gaussian beams is discussed in Sect. 4.1.
