pub const CHOP_AMBIGUOUS_COHERENCE: f64 = 0.5;Expand description
Coherence below which an axis’s chop decision is uncertain; see
SliceChopping::ambiguous_axes.
Smooth phase gives a neighbour coherence near +1, chopped phase near −1. Values close to zero come from data with too little signal, or phase varying too fast between voxels, for the sign to be trusted either way.
