Introduction
============
This data set contains version 2.0 of calibrated spectral images of
comet 9P/Tempel 1 acquired by the Deep Impact High Resolution
Instrument Infrared Spectrometer (HRII) during the encounter phase of
the mission. Version 2.0 includes uncleaned and cleaned radiance data
(RADREV and RAD, respectively) with improved calibration and geometry.
The data were collected from 20 June through 6 July 2005. Spectra taken
before 20 June 2005 are not included in this data set because the
spectrometer was not pointing at the target.
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
