Top: radial profiles of the CH₃OH (v_t = 0) [7(0, 7)–6(0, 6)] integrated intensity maps at 338.1245 GHz for the hot core model cr16-r3-l2 at various timescales. Bottom: radial profile of the CH₃OH (v_t = 1) [7(4, 4)–6(4, 3)] and [7(4, 3)–6(4, 2)] integrated intensity maps at 337.68559 GHz for various hot core models. The adopted distance to the source and the telescope beam size are 2 kpc and 2.2′′.
