5σ injection to the upper dark region of the gvAPP180/Altair dataset and retrieved by choosing reference pixels from the upper dark hole, upper bright side, lower dark hole, and lower bright side.
| Reference pixels | S/N | Contrast deviation (%) | Position deviation (mas) |
|---|---|---|---|
| Upper dark | 5.17 ± 0.73 | 15 ± 7 | 10 ± 3 |
| Upper bright | 3.54 ± 0.51 | 32 ± 22 | 17 ± 13 |
| Lower dark | 1.46 ± 3.24 | 53 ± 64 | 18 ± 11 |
| Lower bright | 1.42 ± 2.66 | 53 ± 80 | 24 ± 7 |
Notes. The results are averaged by five injections at a radial separation of 5 λ/D but at different angles. The uncertainty is the standard deviation of the five injections. The retrieved contrast deviation is relative to the injected contrast. The retrieved position deviation is absolute to the injected position.
