The system is designed to facilitate analyses which require data from multiple instruments and/or multiple spacecraft. The PPI node provides access to a detailed catalog of data sets available from fields and particles experiments on planetary missions. This catalog enables a data system user to determine which data sets are available and to order these data sets. In addition, the PPI node provides an on-line browse function which allows a user to survey a limited subset of data in either graphical or tabular form. The PPI node currently stores data from the Voyager missions to Jupiter, Saturn, and Uranus. Data are available from the magnetometer, the plasma waves experiment, the plasma experiment, and the low-energy charged particle experiment. The PPI node consists of three sub-nodes with the data system located at UCLA. Access to the PPI node is via a wide-area network (NSI/DECNE and telephone dial-up communications. Users of the system are given electronic access to all features of the system, including the detailed catalog and the browse system. The system expects the user to have a VT100 emulator for the catalog and tabular displays and a Tektronix 4014 emulator for graphical displays. Users of the system are asked to record their experiences with the system. This information will be used to aid further development. A users manual has been prepared for version 1.0. Both hard copy and on-line versions of the documentation are available for interested users. For further information please contact Dr. R. J. Walker at the University of California Los Angeles. The distributed sub-nodes of PPI are located at UCLA, the University of Iowa and the Goddard Space Flight Center. Scientific oversight and data for the prototype data system were provided by Dr. Barry Mauk at APL, Dr. John Richardson at MIT, Dr. William Kurth at Iowa, Dr. J. D. Winningham at Southwest Research Institute, Dr. Alan Cummings at Caltech, Dr. A. Kliore at JPL and Dr. R. L. McPherron, Dr. C. T. Russell and Dr. Raymond Walker at UCLA. The data system was developed at UCLA by Mr. Todd King, Mr. Steven Joy and Mr. Neal Cline. The system runs on DEC Vax computers running the VMS operating system. At present the system is implemented on a VAX workstation 3200 which front-ends a Sharebase Intelligent Data Machine. Queries to the Sharebase are written in the Structured Query Language (SQL).
