Introduction
============
This data set contains version 2.0 of calibrated images of comet
9P/Tempel 1 acquired by the Deep Impact Medium Resolution Instrument
Visible CCD (MRI) during the encounter phase of the mission. Version
2.0 includes uncleaned radiance (RADREV), cleaned radiance (RAD), and
I-over-F (IF) data with improved geometry. The data were collected
from 1 May through 6 July 2005.
Volume Format
=============
This volume has been formatted according to the ISO-9660 level 2
Interchange Standard for directories and file names.
File Formats
============
All text documents and other meta information files such as
descriptions, PDS object definitions and detached PDS labels are
stream format files, with a carriage return (ASCII 13) and a line
feed character (ASCII 10) at the end of the record. This allows
the files to be read by various operating systems.
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 some directories for specific information on the files in that
