Struct MotionAverage 

pub struct MotionAverage {
    pub magnitude: Vec<f64>,
    pub phase: Vec<f64>,
    pub contributions: Vec<u32>,
    pub rotation_spread_deg: f64,
}

A complex average of a motion-corrected series.

Averaging phase across volumes acquired at different head orientations averages phase accumulated under different dipole-kernel orientations, so this is an approximation whose error grows with MotionSeries::rotation_spread_deg. It is exactly right for repeats that did not rotate, a good approximation for a degree or two, and the wrong tool once the spread is large enough to matter — at which point the spread is itself the signal, and CorrectedSeries with a per-volume bdir is the honest path.

Fields

magnitude: Vec<f64>

Complex-mean magnitude on the reference grid.

phase: Vec<f64>

Complex-mean wrapped phase on the reference grid.

contributions: Vec<u32>

How many volumes of the series actually reached each reference voxel. 0 means no data, not a zero measurement.

rotation_spread_deg: f64

Rotation spread the average was taken over, in degrees — MotionSeries::rotation_spread_deg, repeated here because it is the number that decides whether the average is trustworthy.
