Abstract :
It is shown that both the Boltzmann and the Gibbs maximum-entropy (ME) methods are appropriate for the underdetermined inverse black body radiation problem. The choice of either or an alternative method is subjective. With a minimum of assumptions they are attractive alternatives to other formally correct but impractical solutions. The ME solutions illustrate, by means of a synthetic data example, the strong dependence of a most probable coldness distribution on measured data.<>
