The MMT Observatory Raw CLIO Observations of the LCROSS Impacts
===============================================================

Introduction
============

   This document provides an overview of this archive, including a 
   description of the volume structure. For complete documentation see the 
   files in the CATALOG directory of this volume.

   This volume contains raw data collected from the MMT Observatory 
   CLIO instrument during observations of the impact of the
   LCROSS spacecraft on the moon on October 9, 2009.

File Formats
============

   Data products in this archive are in the form of FITS images with 
   detached PDS labels. 

   PDS labels (*.LBL), catalog files (*.CAT), and text documents (*.TXT) 
   are ASCII stream format files, with a carriage return (ASCII 13) and a line
   feed character (ASCII 10) at the end of each line.  This allows the
   files to be read by MS-DOS/Windows, Unix and MacOS operating systems.
   
   Index tables (*.TAB) in the INDEX directory are ASCII text files with
   fixed-length records. Columns in the table are separated by commas. 

Volume Contents
===============

   Files on this volume are organized into a set of subdirectories
   below the top-level directory. The following table shows the
   structure and content of these directories. In the table, directory
   names are enclosed in square brackets ([]). See the "*info.txt"
   files in each directory for specific information on the files in the
   directory, including naming schemes.
