^a Lines thermally excited ( $n>n_{\rm {cr}}$ ); ^b lines subthermally excited (n assumed to be 10⁴ cm^-3); ^c red and Blue outflow contributions are calculated by excluding the central 3 km s^-1 emission; ^d errors on the temperatures are 25%, except for temperatures above 150 K, where it is estimated to be at 40%.
