The "data" array is an effective scalar epsilon for each point (which should correspond to a simple mean epsilon for that pixel if you had isotropic materials to start with). The other arrays are components of the epsilon tensor and the inverse tensor, in Cartesian coordinates. Note that even if you start with isotropic materials, MPB uses anisotropic materials internally near material interfaces to improve accuracy, as described in the MPB paper. For most purposes, you just want to look at "data", as in the MPB tutorial.
