reconstructed wavefunctions are not saved, and not even calculated,
AFAIK, because they consist of two pieces: a "smooth" part, expanded
into plane waves, and an "augmentation part", defined on radial grids,
centered around the nuclear positions. The info needed to reconstruct
all-electron orbitals is available, though.

Currently it is possible to plot reconstructed charge densities using
PAW (courtesy of Lorenzo) (PAW, not GIPAW), but you need a very
dense FFT grid to get decent plots.
