Results from the IR − IX point-to-point analysis of the halo.
| Method | Threshold | k |
|---|---|---|
| 2σ | 0.55 ± 0.04 | |
| Bisector | 3σ | 0.51 ± 0.04 |
| 4σ | 0.46 ± 0.04 | |
| 2σ | 0.56 ± 0.04 | |
| Orthogonal | 3σ | 0.52 ± 0.04 |
| 4σ | 0.48 ± 0.04 | |
| 2σ | 0.53 ± 0.05 | |
| Linmix | 3σ | 0.51 ± 0.05 |
| 4σ | 0.48 ± 0.05 | |
Notes. We tested BCES bisector, BCES orthogonal, and linmix methods with various radio thresholds. The obtained slopes k are listed in Col. 3.
