DATA_SET_DESCRIPTION = "NASA's
Voyager Project and Planetary Data System (PDS) have created
an archive of planetary digital images acquired by the twin Voyager
spacecraft (Voyager 1 and Voyager 2). This initial collection includes
all of the images acquired by Voyager 2 as it passed by the planet
Uranus, and selected near-encounter images of Jupiter, Saturn, and
their satellites taken by both spacecraft.
The current Voyager archive resides on eight CDROM volumes. Each
volume contains approximately 2500 images stored in individual files.
The Uranus volumes, (volumes one through three), store the entire
image collection acquired during Voyager 2's encounter with Uranus.
The Saturn volumes, (volumes four and five), and the Jupiter volumes,
(volumes six through eight), contain the best nearest-encounter images
for the respective planets and their moons.
In addition to the images, supplemental information exists on the
CDROMs. This includes documentation providing a user with information
about the organization and contents of the disk. Software source code
is included to provide programmers with tools to process the image
files. There are browse images, sub-sampled versions of the
full-resolution images, which allow users to rapidly view the archive
collection with their interactive display. Finally, there are image
index files containing information about all the images stored in the
archive.
The set of images on the CDROMs are raw; no processing has been
performed other than organizing the original telemetry into
raster-formatted files and compressing the image data using a Huffman
encoding algorithm. To make full scientific use of the image
collection, it is necessary to understand the radiometric and
geometric properties of the camera system and perform corrections to
the data."

INSTRUMENT_DESCRIPTION = "There are two cameras onboard
each Voyager spacecraft, one with a wide field of view and the
other with a narrow field of view. Both cameras return data in
a digital raster-format containing 800 scan lines and 800
samples per scan line. Each picture element (pixel) in the two
dimensional image array is represented as an 8-bit value, and the
value--in the range 0 to 255--is proportional to the amount of light
detected at that point. The cameras are equipped with color filters so
images taken through complementary filters can be combined during
ground processing to produce color images."
