In the November 2012 issue of SLEEP, we published a report on a combined field and laboratory study investigating the impact of night shift work on the operational performance of police officers. We compared performance after the last five consecutive night shifts with the performance after three consecutive days off duty. We used high-fidelity driving simulators to test driving performance, which was quantified in terms of lane deviation (standard deviation of lateral lane position). Due to an error in the software used to calculate lane deviation, the values we plotted in a graph in Figure 1 (panel A) are too small by a factor √2. The corrected graph is provided below. The statistical analyses and inferences are not affected. The authors thank Dr. Dario Salvucci for pointing out the miscalculation, and they regret the error.

睡眠和昼夜节律可穿戴技术：设备验证和应用的考虑因素。

在SLEEP 2012年11月号中，我们发表了一份结合实地和实验室研究的报告，调查了夜班工作对警务人员的绩效的影响。我们将连续五个夜班后的表现与连续三天下班后的表现进行了比较。我们使用高保真驾驶模拟器来测试驾驶性能，并根据车道偏差（横向车道位置的标准偏差）进行量化。由于用于计算车道偏离的软件中的错误，我们在图1（图A）的图表中绘制的值太小了√2。下面提供了校正后的图表。统计分析和推论不受影响。作者感谢Dario Salvucci博士指出错误的计算，并对错误感到遗憾。
