16. In fact the condition Re{?}>0 is somewhat artificial in this case. Equation (27) has two solutions. Exactly the same solutions are obtained if one assumes that |w 1/w 2|<1 but only one of them gives correct physical results. It is also worth noting that, as the time dependence of the temperature is taken in the form exp(?i?t), the average surface temperature is ?T?=Aexp(?i?) where ? is the phase measured during the experiments
