Overview

The Voyager Imaging Science Subsystem (ISS) consists of two cameras, narrow-angle and wide-angle. Images have been archived in chronological volumes based on Voyager's Flight Data System ("FDS") clock which is also the basis for the root filenames of the images.

The ISS Tabs

The tabs associated with this page describe the ISS data files and how to obtain them.

• Instrument - Access to descriptive information about the Voyager cameras.
• Raw Images - Access to all of the Voyager images in raw, compressed format.
• Calib Images - Access to volumes containing all of the Voyager images from the Saturn encounter in raw, calibrated, and geometrically corrected formats. Users are advised to use caution. This data set has not yet completed peer review.

  Additional volumes will be prepared in the near future covering the Uranus, Neptune and Jupiter encounters.

• Search - Catalog search engines which allow you to identify desired images based on a range of parameters.
• Derived Products - Provides direct access to:
  • All of the Voyager images of the Jovian rings.
  • a set of derived, Saturn Ring, radial profiles from the finest-resolution Voyager images. Profiles of both the lit and dark sides are included at a resolution of order 5 km.

Data Set Information

The PDS originally released raw, compressed "EDR" versions of all the Voyager images on a set of CD-ROMs identified VG_0001 through VG_0038. These volumes can accessed through the Raw Images Tab. The organization is as follows:

• VG_0001-0003: The complete Uranus images
• VG_0004-0005: Selected Saturn images
• VG_0006-0008: Selected Jupiter images
• VG_0009-0012: The complete Neptune images
• VG_0013-0025: The complete Jupiter images
• VG_0026-0038: The complete Saturn images

The PDS Rings Node has produced a new multivolume Voyager ISS data set. It currently includes all the ISS data from the Saturn encounter. Volumes for the Uranus, Neptune and Jupiter encounters will be prepared in the near future.

The volume IDs are VGISS_xxxx as opposed to the originally distributed volumes with IDs VG_xxxx. Each volume in the new data set contains raw, calibrated and geometrically corrected versions of Voyager images. There is a one-to-one correspondence between the calibrated volumes and in their counterpart volumes in the originally distributed, raw only, data set (e.g., VGISS_0004 covers exactly the same FDS range as VG_0004). These volumes can accessed through the Calib Images Tab.

General Image Naming Conventions

• For Jupiter, images beginning with 1 are from Voyager 1 and those beginning with 2 are from Voyager 2
• For Saturn, images beginning with 3 are from Voyager 1 and those beginning with 4 are from Voyager 2.
