Data Set Overview
=================
This data set includes Voyager 2 Saturn encounter magnetometer
data that have been resampled at a 9.6 second sample rate. The
data set is composed of 6 columns: 1) ctime - this column
contains the data acquisition time. The time is always output
in the ISO standard spacecraft event time format
(yyyy-mm-dd-Thh:mm:ss.sss) but is stored internally in Cline
time which is measured in seconds after 00:00:00.000 Jan 01,
1966, 2) br - this column contains the radial component of the
magnetic field, 3) bphi - this column contains the phi
component of the magnetic field, 4) btheta - this column
contains the theta component of the magnetic field, 5) bmag -
this column contains the magnitude of the magnetic field, 6)
flag - a flag value that indicates either software error or
spacecraft hardware interference reduced confidence in this
record (flag value of 1 is bad , 0 is good or unchecked). All
magnetic field observations are measured in nanoTeslas. The
coordinate system for this dataset is Minus Saturn Longitude
System (-SLS). All of the magnetic field data are calibrated
(see the instrument calibration description for more details).
The SLS coordinate system is defined in Desch and Kaiser, 1981
and the reference documents for this dataset are: Ness et al,
1982 Acuna,Connerney,and Ness, 1983 Connerney,Acuna,and Ness,
1983 Behannon,Lepping,and Ness, 1983

Overview
========
This dataset contains some data gaps and spikes. The dataset
does contain a flag value which has been provided by the PI
(Norman Ness) that indicates whether or not a particular record
has been contaminated by software error or by spacecraft
interference ( a flag value of 1 indicates a bad value, 0
indicates that the record has either not been evaluated or is
good). Some records that are obviously contaminated have not
been flagged. The hourly summary data will show a
contamination code and data quality code of 2 when data in the
hour have not been flagged but are obviously in error and a
contamination code of 1 when the hour contains flagged records.
