Comparison of the rotational diagram for the OH lines measured from Ser SMM1 (black diamonds) and a RADEX model with the source continuum included in the excitation (red plus signs) and a model without the continuum field of the source (blue plus signs). The model fluxes were scaled such that they match the observed 84.60  μm emission. The model including the continuum field reproduces the higher excited lines better than the one without.
