--------------------------------------------------------- NSSDC Master Catalog Display Data Set --------------------------------------------------------- Voyager 1 Solar Wind Plasma Data Archive, Final NSSDC ID: 77-084A-06N Mission Name: Voyager 1 Experiment Name: Plasma Spectrometer (PLS) Availability: Data at NSSDC Ready for Distribution Time Span: 1977-09-07 to 1980-12-31 (as determined by NSSDC) Description This data set contains hourly average key parameters for interplanetary cruise data acquired by the Voyager 1 Plasma Science (PLS) experiment. The data are written in ASCII format and provided in files named VY1PLA_KEY_xxyy.DAT, each covering one year of data for year yy in century xx (e.g., xxyy = 1980). Each key parameter record includes year, day, hour, proton speed (km/s), proton density (#/cc), proton thermal width (km/s), where proton temperature T(eV) = 0.0052(width)**2, and alpha density (#/cc), as well as proton bulk speed and vector components (Vr, Vt, Vn) in the RTN coordinate system. In RTN the R axis is outward from the Sun to the spacecraft, T is the cross product of the solar rotation axis and R, and N completes the orthogonal system. For hourly averages the hour is an integer, otherwise it will will have a fractional part for data from higher resolution PLS spectra. All parameters are derived from a nonlinear fit calculation. A parameter E1 (if present) gives the sum of currents for electrons. These cruise data were obtained from the MIT Plasma Group's anonymous FTP site at mit.space.edu/pub/plasma and were accompanied by spacecraft SEDR ephemeris data cataloged at NSSDC under data set ID 77-084A-00G. ------------------- Discipline(s) Space Physics/Heliospheric Studies Archive Locations National Space Science Data Center (National Aeronautics and Space Administration) Media Information 1 Digital Magnetic Tape --------------------------------------------------------- NSSDC Master Catalog Display Data Set Personnel --------------------------------------------------------- Voyager 1 Solar Wind Plasma Data Archive, Final NSSDC ID: 77-084A-06N General Contact Prof. John W.
