Strange indeed Robin, and suprising as the are both experts on red supergiants. Indeed EML has written a book on the astrophysics of Red Giants!
Maybe the IR bands are more sensitive to Teff than in the V . I will look at her book and see if I can find any comment on it.It will be interesting to see how the discussion develops.
