The Low Energy Charged Particle (LECP) experiment has provided two datasets
from the Neptune encounter. The first dataset contains 24 second scan averages
for each of 15 channels. The seconds dataset contains full sweep or step
data which gives directional information about the particle distribution. 
These two datasets are contained in the SCAN and STEP sub-directories. 

          Voyager 2 LECP Pitchangle data near Neptune.

There is a pitch angle dataset which gives the angle each sector made
with the local magnetic field as a function of time. This dataset is
ancillary to both datasets provided by the instrument team. 
The data are averaged to 48 second resolution and cover the time 
period 1989-08-24T18:00:47 to 1989-08-25T15:59:59.

The dataset is formed by a collection of 6 files.  The data are stored as an 
IGPP flatfile (4 individual files).  The data are in the ".DAT" file which is 
described to the PPI software by the ".DES", ".ABS", and ".HED" files.  The 
PDS label file PITCHANG.LBL describes some of the physical properties of the 
pitch angle dataset and the dataset format file PITCHANG.FMT describes the 
columns of the dataset.
