Notes.

^(a)

Cloud number defined by the different velocity components.

^(b)

We only consider the warm component of the para-NH₃ with the ortho-NH₃ (see text for details).

^(c)

This value was not considered in the average of the ortho-to-para ratio, because it is possible that this position does not have the high kinetic temperature regimen.
