Map of the CH₃OH-E column density (bottom panel), temperature (top panel), and density (central panel) of the gas emitting the methanol lines in the northern cloud, which is shown in Fig. 1, as derived by the non-LTE analysis described in Sect. 6.4. The size of the beam (30″) is shown by a white filled circle at the bottom right of each map, the position of the protostars are represented by white stars. We note that the average error bar in the derived temperature is 5–10 K; in the density, it is a factor of two and in the CH₃ OH-E column density, it is 3 × 10¹³ cm⁻³.
