We consider two toy models of open inflation and investigate their ability to
give a suppression of scalar power on large scales whilst also satisfying
observational constraints on the spatial curvature of the universe.
Qualitatively we find that both models are indeed capable of fulfilling these
two requirements, but we also see that effects of the quantum tunnelling must
be carefully taken into account if we wish to make quantitative predictions.Comment: 11 pages, 13 figures. Updated to match published version: figures 7
