Uncertainty budget for the comparison of dwell positions from different catheter reconstruction techniques relative to the SPS source for the VeneziaTM lunar ovoids, including Type A uncertainty terms based on repeated measurements and Type B uncertainty based on corresponding data
| Type A (mm) | Type B (mm) | |
|---|---|---|
| SPS repeatability from CT scans | 0.1 | – |
| SPS agreement with 192Ir source | 0.3 | – |
| Catheter reconstruction method | – | 0.1 |
| CT registration accuracy | – | 0.4 |
| Combined uncertainty (k = 1) | 0.5 | |
| Expanded uncertainty (k = 2) | 1.0 | |
