The equilibrium E- to A- methanol ratio as a function of nuclear spin temperature (solid curve). Ratios <1 observed towards our sources are plotted as stars according to this relation, errorbars indicating effect of a 10% difference in the assumed Tex for A-methanol. Horizontal arrows represent sources where ratios >1 according to the y-scale, and are drawn from the equivalent spin temperature of the lower errorbar.
