This dataset contains Pioneer Venus Orbiter (PVO) spacecraft 
position and orientation data in Venus Solar Orbital (VSO) 
coordinates. This dataset is sampled every 12 seconds near
periapsis, and at 1 minute or 10 minute rates in the solar wind,
the lowest rates near apoapsis.  Planetocentric and heliocentric 
position vectors and solar zenith angle (Sun-Venus-PVO) are also 
provided. The VSO parameters are derived from the PVO Supplemental
Experimenter Data Records (SEDR), other parameters are taken
directly from the SEDR dataset.

This dataset is used by the program PVROT to transform magnetic
field vectors from Inertial Spacecraft Coordinates (ISC) to
VSO Coordinates. Please refer to the coordinate system template
for definitions of these two coordinate systems."

contains parameters which are either taken directly from the
