1  AAIJ 2019AG reports [${{\mathit \Xi}_{{{c}}}^{+}}$ MEAN LIFE] $/$ [${{\mathit D}^{\pm}}$ MEAN LIFE] = $0.4392$ $\pm0.0034$ $\pm0.0028$ which we multiply by our best (shown rounded) value ${{\mathit D}^{\pm}}$ MEAN LIFE = ($1.033$ $\pm0.005$) $ \times 10^{-12}$ s. Our first error is their experiment's error and our second error is the systematic error from using our best (shown rounded) value.
