Dear Helen,
    sorry for the delay of this reply, but I think that this discussion is
very important: can you really really exclude a hot emission component
down to 3 orders of magnitude below the highest signal in the UV band?
Are uncertainties so small? What is the confidence of this result? Can
you provide a quantitative upper limit? Is this result published and
can you provide a reference (it is very important)?
Best regards
Fabio
