Comparison between the α-angle and the power law methods for disk detection.
| α-angle method | ||||
| Disk | No disk | |||

| Power law | Disk | 42% | 7% | 49% |
| method | No disk | 11% | 40% | 51% |
| 53% | 47% | |||
Notes. To claim detection of a disk, using the α-angle method, we require that 0 ≤ α ≤ 0.2 π/ 2. To claim detection of a Keplerian disk, on scales between 50 AU and 150 AU, using the power law method, we require the power law exponent to fall into the range 0.25 ≤ β ≤ 0.75 and R2> 0.8.
