The Dawn Science Plan document. This document provides a description of the   
as flown Dawn observations throughout the mission from launch through Vesta.  
It is also provided as a source of information on the intent of the           
observations planned for at Ceres. Note that not all of the planned           
observations actually occurred due to a variety of instrument resets and      
spacecraft safings, etc.
