The DOCUMENT directory contains copies of documents that are necessary or     
useful for users to understand the archive data set. These documents are      
orgainized in the subdirectories listed below.

This directory contains reports describing instrument operations and results  
of the various instrument activities and observations. Each report is located 
in a subdirectory whose name is identical to that used in the DATA directory  
for the corresponding data. Most, but not all activities have reports.

The Dawn Framing Camera Calibration Pipeline description document. This       
document describes the pipeline for calibration of the images acquired by     
both models of the DAWN Framing Camera (FC1 and FC2). It details its          
operation and implementation. The pipeline builds on the results of the       
analysis of in-flight [1] and laboratory measurements [2-5]. [Schroeder &

The Dawn Framing Camera Software Inferface Specification (SIS). This document 
describes the contents and types of archive volumes belonging to all of the   
FC1 and FC2 NASA level 1 (CODMAC levels 2 and 3) data sets. This includes     
detailed descriptions of the data formats to allow users to read the data     
products.

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