Hi Roberta,

   Attached is my first pass at the SED fitting for visual, 2MASS, and WISE data on some of the red supergiants from the Drout sample in M33.  Many of them seem to exhibit an infrared excess (although I don't completely trust the WISE-band data yet--I couldn't find consistent zeropoints for the mag-to-flux conversion).

   My next step is to correct for extinction--we should discuss how you did that in your Paper II on the M31/33 LBV candidates.  Correcting for extinction in the visual bands will greatly boost the blackbody temperature fit past 10,000 K for most of these stars, which will then be consistent with the literature.

   Finally, I want to try multi-component blackbody fits for the infrared part of the SED.  Valeev et al, 2010 (Figure 3 in http://arxiv.org/pdf/1009.1165v1.pdf) demonstrate a two-component dust model with warm (1000K) and cold (480K) elements.
