Data Fields

HDF5 arrays are loaded sample-first by src/sparsewake/data.py.

Field Loaded shape Description
X_raw [N, 6, 3] Wake-plus-potential per-sensor induced velocity features.
X_wake_raw [N, 6, 3] Wake-only component where available.
X_potential_raw [N, 6, 3] Potential-only component where available.
X_external_raw [N, 6, 3] External neighbor signal in self-signal datasets.
X_self_raw [N, 6, 3] Self-generated signal in self-signal datasets.
X_total_raw [N, 6, 3] External-plus-self signal in self-signal datasets.
y [N, 6] delta_x, delta_y, theta_rel, sin_phi, cos_phi, phi.
groups [N] Wake phase index.
pose_id [N] Pose index for pose-holdout when present; otherwise derived from phase blocks.
region_id [N] Region code: 1 close wake, 2 near side, 3 mid wake.
sensor_world_positions [N, 6, 2] Sensor coordinates for each sample.

Raw velocity feature channels are body-frame u, body-frame v, and speed magnitude.
