Dipper fractions for the three regions with well-studied dipper populations. The Upper Scorpius association and ρ Ophiuchus cluster have been added in this work. The dipper fraction quoted here is as a function of disc-bearing stars only.
| Region . | Age . | Disc fraction . | Dipper fraction . | Dipper Number . |
|---|---|---|---|---|
| ρ Ophiuchus | 0.1–1 Myr (Luhman & Rieke 1999) | 40.2 per cent ± 4.3 per cent | 20.1|$\,{\rm per \, cent} \pm 4.3\,{\rm per \, cent}$| | 22 |
| NGC 2264 | 1–5 Myr (Rebull et al. 2002)Dahm (2008) | 12.8 per cent ± 1.0 per cent | 21.6|$\,{\rm per \, cent} \pm 3.7\,{\rm per \, cent}$| Cody et al. (2014) | 35 |
| Upper Scorpius | 10 Myr (Pecaut et al. 2012) | 26.7 per cent ± 2.0 per cent | 21.8|$\,{\rm per \, cent} \pm 3.4\,{\rm per \, cent}$| | 42 |
