|---|---|---|---|---|---|
| ETΔ | 10 | Triangular | Sardinia | 85% | 12 |
| ET2L | 15 | 2L-Shaped (45° misalignment) | Sardinia & Meuse-Rhine | 85% | 12 |
| ETΔ+2CE | 10 (ET), 40 & 20 (CE) | Triangular + 2 CEs | Sardinia (ET), US (CE) | 85% | 12 |
| ET2L+2CE | 15 (ET), 40& 20 (CE) | 2L-Shaped + 2 CEs | Sardinia & Meuse-Rhine (ET), US (CE) | 85% | 12 |
Notes. The interferometer assumptions include arm length, configuration type, location, duty cycle and the applied S/N threshold.
