Unclear why `np.transpose` is being called on a `list`

Lines 334 to 336 in 909d32a

	free_energy=np.transpose(free_energies),
	entropy=np.transpose(entropies),
	cv=np.transpose(heat_capacities),

The types for free_energies, entropies, and heat_capacities are stated to be list, so I am not sure why np.transpose() is being called. But because I do not understand why it's there in the first place, I do not feel comfortable changing it.
