Table 2
Our measurements of the time delays of HE 0435−1223 from two independent datasets.
| Time delay | Courbin et al. (2011) a | Blackburne et al. (2014) | Weighted average |
| (days) | (days) | (days) | |

| ΔtAB | 8.4 ± 1.4 | 12.3 ± 1.9 | 9.8 ± 1.1 |
| ΔtAC | 3.6 ± 3.4 | 2.7 ± 2.9 | 3.1 ± 2.2 |
| ΔtAD | 13.1 ± 1.1 | 15.8 ± 2.1 | 13.7 ± 1.0 |
| ΔtBC | −8.3 ± 1.5 | −7.7 ± 1.4 | −8.0 ± 1.0 |
| ΔtBD | 5.7 ± 1.7 | 7.9 ± 3.2 | 6.2 ± 1.5 |
| ΔtCD | 13.0 ± 1.1 | 14.1 ± 1.1 | 13.6 ± 0.8 |
Notes.
The SMARTS data points were excluded from the light curves of Courbin et al. (2011) so that the measured time delay values were independent of those measured from the SMARTS monitoring light curves of Blackburne et al. (2014; see discussion in Sect. 3).
