Table 4
Percentage of helium WDs and carbon/oxygen (including oxygen/neon) WDs in visible PCEBs in the SDSS for different models of CE evolution.
| He WD | CO WD | |

| Model γα1 | 72 | 28 |
| Model αα1 | 75 | 25 |
| Model γα2 | 83 | 17 |
| Model αα2 | 68 | 32 |
| Observeda | 33−46 | 54−67 |
Notes.The percentages in the PCEB population that is found by SDSS are similar to the percentages of the full sample of Zorotovic et al. (2011b) that is given here. The observed type of the WD is determined by its mass with a limiting mass of 0.5 M⊙ for helium WDs, which is consistent with our models. The range in the observed percentages is caused by a few systems in which the stellar type could not be determined unambiguously.
