Notes. This table summarises the values from the observations which are referenced for the RADEX modelling.

(a)

The velocity-integrated brightness temperatures of H2S 11, 0 − 10, 1 transition.

(b)

The velocity-integrated brightness temperatures of H2S 22, 0 − 21, 1 transition.

(c)

The ratios of (a) to (b).

(d)

The FWHMs of each line, from a Gaussian fit.
