Abstract
The optics error budgets for the W.M. Keck Observatory natural guide star (NGS) and laser guide star (LGS) adaptive optics (AO) facilities' are presented. The purpose of generating this error budget2 is three-fold: (1) to summarize the error sources which will contribute to the degradation of images on a science instrument fed by the AO facilities, (2) to compare the predicted performance with the requirements, and (3) to provide a tool for evaluating potential engineering, and observing, trade-offs.
