The LIME output (left column) and corresponding ALMA simulations (right column) of the disk model example presented in Sect. 4. Panels a) and b) show the disk face-on in HCO⁺J = 7–6, panels c) and d) show the disk edge-on in H₂O J = 3₁₃–2₂₀, and panel e) shows the average A- and E-CH₃OH spectrum as well as a couple of SO₂ lines which falls in this window. Panel f) is an ALMA simulation similar to the one in panel d), but for only 6 antennas. The ALMA simulations shown in panel b) and d) corresponds to 2 h tracks with the full array. The noise level in both simulations is about 2.5 × 10^-7 Jy beam^-1. The simulation in panel f) is for a much more compact ALMA configuration with a noise level of 0.2 × 10^-7 Jy beam^-1.
