The beta release of the Rings Node Ephemeris Generator 2.0 is now available from the tools page. It includes the capability to tabulate the sub-Earth and sub-solar latitude and rotating longitude for any planet or moon. We have also revised the user interface. The new generator has been tested extensively, but may undergo further changes before official release. Comments welcome.
All of the Rings Node's tools have been updated for the leap second of December 31, 1998. In addition, version 1.3.1 of the Julian toolkit now includes this leap second.
Galileo NIMS spectral image cubes of the Jovian ring are now available.
Galileo SSI ring images from the C10 encounter are now available.
Galileo SSI ring images from the G8 encounter are now available.
A revised and updated version of the Julian Toolkit is now available. The Julian Toolkit performs a variety of date and time conversions. In addition, the entire source code is on-line for documentation purposes.
The Rings Node Toolkits page has been reorganized. In addition, the powerful new Profile Toolkit 1.0 is now available. It simplifies the access and manipulation of all ring occultation data sets archived at the Rings Node. It provides facilities for applying geometry solutions to the data, calibrating, filtering and resampling the data. It can be accessed called from programs written in either C or FORTRAN-77. In addition, the self-documenting code is entirely on-line.
The first set of Galileo Jovian ring images are now available in support of NASA's Jovian System Data Analysis Program. Also included are the analogous images from Voyagers 1 and 2.
