Unblended or only slightly blended emission lines (red asterisks) of syn-HOCH₂C(O)NH₂ toward G358.93 MM1. Black lines show the observed spectra, while red lines represent the LTE model of syn-HOCH₂C(O)NH₂. Blue lines correspond to a composite model that includes contributions from all other identified molecular species. Dashed green lines mark the 3σ noise level. The upper-level energies (E_u) of the transitions are given above each panel.
