Notes. Eight pixels in E-W strips across the central source of AFGL 2591, and one off-source, were taken and fit with RADEX, a non-LTE model. These are labelled in black and white in Fig. 7. Two components were fit to each pixel’s spectra. A- and E-CH3OH are used in this model due to the availability of collisional co-efficients. There are not enough lines to determine the A-/E- ratio, thus it is assumed to be 1.
