| SMC-CEP-3674 | 4500 ± 40 | 2630 ± 70 |
| SMC-CEP-2699 | 4160 ± 60 | 2400 ± 80 |
| SMC-CEP-3115 | 8900 ± 800 | 9300 ± 2300 |

Notes. Orbital period (Porb) and reference time (T0, orb) for double Cepheids with anitcorrelated variability of the components (marked LTTE in Table 2). For OGLE-SMC-CEP-3115, the full cycle is not covered and the parameters are highly uncertain.
