This directory contains the 4 second and 48 second res. wave electric
field intensity data from the Plasma Wave instrument on Voyager 2.
These data were recorded from the Saturn encounter period of 1981-08-24
to 1981-08-31. It also contains the calibration data.
The 4 second data are stored as a VAX binary file (.DAT), accompanied
by a PDS label (.LBL) which describes properties of the data file. The
48 second data are stored as an ASCII table, accompanied by a PDS label
file. The calibration data are in an ASCII table used for converting
the uncalibrated 'data numbers' contained in data files to calibrated
volts. A PDS label (SA_CL.LBL) is also provided for this file.
Additional information associated with this data set is available in the
following files:
