The same as Figure 2 but for a mock dataset with two instruments; one with 55 s exposures and one with variable 180 ± 30 s, which frequently overlap. Again, the two methods generally agree to within the expectation from numerical precision. Numerical stability in the variance may be improved with square-root filters (e.g., F. Yaghoobi et al. 2025).
