@djkirkham We have a soft coding standard where we use ma instead of np.ma, see here.

If it's not too much trouble, could you adopt this please, thanks.

nstats = np.array((stats.get('mean', 0.), stats.get('std', 0.),
stats.get('max', 0.), stats.get('min', 0.)),
dtype=np.float_)

@djkirkham Here is well ... np.ma.is_masked(data) -> ma.is_masked(data)

('mean', np.float_(data.mean()))])
