I apologize in advance if this is not the correct place to post this. I am currently writing a paper in no-scale supergravity inflation, and now that the Planck 2015 results are here, it would be nice to use them to constrain the parameters of the model. I am in particular interested in the scalar tilt and the tensor-to-scalar ratio. However, I have absolutely no idea on how to read and analyze the data from Planck. I have set as my most basic goal to reproduce the 68% and 95% CL TT+lowP+BKP+BAO curves of figure 54 in the "constraints on inflation" paper, 1502.02114, but I don't even know where to start. I am aware of the existence of the Planck Legacy Archive, but I can't make sense of the 'explanatory supplement'. Any help will be appreciated.
