Native-grid review: native grid 144x144, no smoothing-only substitution.
PPA Biot-Savart v3 Visual Review Candidate
Source candidate: data/output/tool_checks/biot_savart_thinwire_v3_ordered_wires_candidate_20260506_124508
Are 144-grid v3 NPZ maps visually reviewable?
yes for technical review
Decision basis
Native saved grids are 144x144 across 32 branches; ordered-wire overlays are present; native nearest-neighbor panels, ROI contours, masks, and coil context are generated.
Another higher-resolution recompute required?
no
Suggested max-grid if later required
216 if later reviewer finds the 144-grid native panels still too blocky; otherwise not required
Native grid disclosure
Every figure title states the native saved grid. Images use nearest-neighbor display; no smoothing is applied.
g-like scale
local_g_map and pmr_noise_amp_map use 1 to 5; values above 5 are clipped and marked with a magenta boundary when present.
alias correlation scale
alias_col_corr_map uses 0 to 1.
Contour overlays
full_valid, inner60, central_band, deep_band, and alias_valid_only are drawn where non-empty.
Ordered-wire overlay
Ordered-wire geometry was projected onto every review panel.
