Notes.

(a)

Values derived from single temperature component fit due to the non-detection of the S(1), S(2) and S(8) lines in these apertures.

(b)

OPR equilibrium value of 3.0 assumed due to the non-detection of the S(1) and S(2) transitions in apertures A and B. For aperture C, an OPR ratio of 3 led to a better fit, and is therefore used.
