| 1 | [0.40, 0.55] | 1.18 | 0.384 | PASS |
| 2 | [0.55, 0.70] | 1.78 | 0.022 | ANOMALOUS |
| 3 | [0.70, 0.85] | 0.87 | 0.758 | PASS |
| 4 | [0.85, 0.95] | 0.65 | 0.932 | PASS |
| 5 | [0.95, 1.05] | 0.88 | 0.752 | PASS |
| Hypothesis | Scanned | Failures | Viable? |
|---|---|---|---|
| Photo-z Bias | 21 | 0 | No |
| Magnification | 15 | 0 | No |
| Galaxy Bias | 16 | 0 | No |

Covariance Misestimation
The anomaly is isolated to bin 2. Only covariance modeling produces PPD failures.
