Introduction
============
This dataset contains calibrated, 1.05- to 4.8-micron spectral images
of comet 103/P Hartley 2 acquired by the High Resolution Infrared
Spectrometer (HRII) from 01 October through 26 November 2010 during the
Hartley 2 encounter phase of the EPOXI mission. Version 2 includes a
new per-pixel linearity correction treatment and its propagation
through the calibration steps (i.e., bad-pixel maps, flat-field file
update, revised spectral calibration curve), new mode-dependent master
darks, an optimized scaling factor for the master dark, and a
refinement in the absolute spectral calibration curve.
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.
