16. Solving Eq. (4) numerically without the approximate formula for (Formula presented) it can be shown that formula (6) is accurate within (Formula presented) over the whole temperature interval.

25. The divergence in τ appears approximately 5–8 K below (Formula presented) Possibly this is due to a nonuniform temperature profile within illuminated area.

27. Here the term temperature-independent gap means that the gap does not vanish at (Formula presented) but persists above (Formula presented) It does not exclude the possibility of a weakly temperature dependent gap.
