Some notes on Errors

In discussing the methods of measuring angles and later when discussing directions, reference will be made to "errors". Errors are not mistakes. Errors are a measure of accuracy. Many of the methods discussed are very practical techniques. Like most things practical, there is a component of error which is a result of how well the technique is performed (Personal Error), and there is a component or error that is inherent to the method (Inherent Error). No matter how well a technique is performed, the accuracy can never be better than the inherent error in the method. Unless noted otherwise, all references to errors will mean the inherent error in the method: personal errors (due to how well the technique is performed) are added on top.
