在不同版本的Quanterra数据记录器中，由软件错误引入了系统性和可纠正的定时错误。在各种网络(如GEOFON)中，这种计时误差仍然没有记录在案，但通常在世纪之交之前通过软件升级得到纠正。这个问题对黄体生成素通道来说很重要，我们所有的数据都得到了适当的修正。许多台站也有定时不稳定的周期，这可能是由于失去外部定时标准。这些数据已从进一步的分析中删除。
Timing Errors Systematic and correctable timing errors were introduced by software bugs in various versions of the Quanterra data logger. Such timing errors remained undocumented at various networks (e.g., Geofon) but were generally fixed by software upgrades before the turn of the millennium. This problem was significant for the LH channels, and all our data have been appropriately corrected. Many stations also have periods of erratic timing which are likely due to loss of an external timing standard. Such data have been removed from further analysis.
