1  AAIJ 2019AG reports [${{\mathit \Xi}_{{c}}^{0}}$ MEAN LIFE] $/$ [${{\mathit D}^{\pm}}$ MEAN LIFE] = $0.1485$ $\pm0.0017$ $\pm0.0016$ which we multiply by our best value ${{\mathit D}^{\pm}}$ MEAN LIFE = ($1.040$ $\pm0.007$) $\times 10^{-12}$ s. Our first error is their experiment's error and our second error is the systematic error from using our best value.
