| 1 | 694 (452–999) | 330 ± 201 | 1,140 (751–1,617) | 578 ± 307 |
| 2 | 708 (536–999) | 199 ± 97 | 1,147 (885–1,621) | 379 ± 135 |
| 3 | 709 (560–863) | 157 ± 73 | 1,132 (908–1,361) | 329 ± 82 |
| 4 | 706 (642–845) | 136 ± 56 | 1,117 (1,029–1,298) | 312 ± 68 |
| 5 | 699 (669–757) | 123 ± 32 | 1,099 (1,045–1,174) | 301 ± 39 |
| 6 | 695 (—) | 119 | 1,085 (—) | 309 |
Mean ages, range of ages, and mean 95% credibility interval widths (δ Credl) are computed on the 6, 15, 20, 15, 6, or 1 possibility of incorporation of, respectively, C = 1, 2, 3, 4, 5, or 6 simultaneous calibrations.
