Comment (by hinder):
Interpolation within Carpet (i.e. for prolongation, which is separate from that provided by AEILocalInterp) is tested using a polynomial for which interpolation of the correct order (at least for some interpolators) is exact. This means that the correct solution is trivial and it's obvious if the test is correct or not. I propose some sort of initial data thorn for setting polynomial initial data which could be used by the testsuites for the interpolator. This would be part of Cactus, as it is sufficiently generic and useful for testing interpolator thorns. I don't think we should use an Einstein-based initial data thorn for testing the interpolators. This belongs in Cactus, not the ET.
