Introduction
============
This dataset contains calibrated narrow band filter images
(350-950 nm) images of Mars acquired by the Deep Impact High
Resolution Visible CCD (HRIV) for the EPOCh project during the second
cruise phase of the EPOXI mission. One set of observations was
acquired on 20-21 November 2009 to characterize Mars as an analog for
extrasolar planets. The observing period lasted approximately 24
hours. HRIV images were acquired once per hour with the filters
centered on 350, 750 and 950 nm, whereas the 450-, 550-, 650-, and
850-nm data were taken every 15 minutes. Version 2.0 includes the
application of a horizontal destriping process and revised electronic
crosstalk calibration files.
Volume Format
=============
This single-volume dataset has been formatted according to the ISO-9660
level 2 Interchange Standard for directories and file names as described
in Version 3.7 of the PDS Standards Reference.
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 single-volume dataset are organized into a set of
subdirectories below the top-level directory. The following table shows
the general structure and content. The top-level of the volume is
indicated by a single forward slash (/) and subdirectory names are
surrounded by forward slashes (/). See the *INFO.TXT files located in each
subdirectory for specific information about the contents the subdirectory.
