Sorry for asking a stupid question, but I have some difficulties interpreting figure 2 in this paper. In particular, what does the black, solid line show?

Thanks -- and again, sorry..

As already discussed in the e-mail correspondence, the black line is a vanilla 0.3-0.7 model with normalisation that is somewhat low wrt to WMAP best fit - since it is for illustrative purposes only, it doesn't really matter in my view.
