double HyperfineTspin

(

const TransitionProxy &

t

)

HyperfineTspin

Compute spin (excitation) temperature for HFS line. The spin temperature is always finite (> 0, or < 0 if masing). The kinetic temperature is used if the spin temperature evaluates to 0, or if the upper limit has a population that is too small (~< 2e-36 cm^-3) to reliably compute the spin temperature.

Parameters

t	[in] Transition

Returns

Tspin
