    added the famous figure 1 to the entry, the dataset that was confirmed by the measurements published yesterday. It’s the following. The Starobinsky model is the orange line, labeled “R 2R^2-inflation”

    Probably you mean the graphics in comment #2 above. Works fine for me. Which browser are you using? Maybe Richard has some advice.

    Hm, I have version 62. Maybe that makes the difference? Strange.

    But I have shrunk the picture now. Does it work now? Not that it is very important to have that graphics here on the forum….
