Phase Error Burst Alignment: kilauea_year_e2e_pack_fast_stage2_20260428
Oracle, MLX-generated products, differences, timing and quality gates share one evidence layout.
Conclusion
The wrapped phase.grd error is summarized against TOPS shifted-writer seams and SAFE burst starts. High row resultant length means the error is coherent across range for a given azimuth row; peaks in row circular-mean gradient indicate abrupt horizontal phase changes.
| phase mean abs rad | 0.00631364 |
|---|---|
| phase rmse rad | 0.0174297 |
| row resultant median | 0.999944 |
| column resultant median | 0.999947 |
| top 10 peaks within 3 rows of writer seam | 7 |
| top 10 peaks within 3 rows of SAFE burst start | 0 |
| near writer seam mean abs rad | 0.00935083 |
| away from writer seam mean abs rad | 0.00623796 |
Error With Burst Overlays
Black lines are TOPS shifted-writer output seams. Gold lines are SAFE burst-start positions mapped into the stage-4 phase grid.
