31. Magnetic field fluctuations ( a significant source of systematic error ) were monitored using atomic mercury magnetometer. 32. Because during that time, the statistical errors from the data are negligible, the systematic errors will dominate. 33. "I don't think there are systematic errors . 34. Incorrect zeroing of an instrument leading to a zero error is an example of systematic error in instrumentation. 35. Averaging measurements as described above lead to comparable results because they include the same amount of systematic errors . 36. The result is that, in practice, data reconciliation is mainly making adjustments to correct systematic errors like biases. 37. But, he added, " The truth is, the butterfly ballot causes confusion and systematic error in voting ." 38. The need to control and measure all the sources of systematic errors required a rigorous and integrated design. 39. This then means any further signal is due to the phenomenon being detected and not a systematic error . 40. Additional measurements will be of little benefit, because the overall error cannot be reduced below the systematic error .
