DATA_SET_DESCRIPTION
Voyager 1 plasma data of the solar wind, fine resolution data.
The files in this directory contain the Voyager fine resolution plasma data.
The plasma parameters are obtained by finding the best fit of a convected
isotropic Maxwellian distribution to the data. One sigma errors
are typically less than 0.5 percent in the speed and VR, less than 5 percent
for the density and thermal speed, and vary greatly for VT and VN.
Sampling times range from 12 to 192 sec., with sampling generally more
frequent early in the mission. The columns are:
1) Year
2) day of year (day 1 is Jan. 1)
3) decimal hour
4) proton speed in km/s, magnitude of the velocity vector
5) proton density in cm-3
6) proton thermal speed in km/s (proton temperature in eV = .0052 times the
square of the thermal speed)
7) Radial Velocity (along the spacecraft/Sun direction) in km/s
8) Tangential Velocity (parallel to the solar equatorial plane and
perpendicular to the radial direction) in km/s
9) Normal Velocity (perpendicular to the VR and VT directions) in km/s
The velocity components are given in the RTN coordinate system,
where R is radially outward, T is in a plane parallel to the solar
equatorial plane and positive in the direction of solar rotation,
and N completes a right-handed system.
If possible, please consult with us, or at least send preprints, when you
use this data to prevent grievous errors or misconceptions.
