PVO Electron Temperature Probe (OETP) low resolution data.
The data cover orbits 1-2500, however, data is not available for
all orbits.

Useful Files:
DATASET.TXT     (describes the dataset)
UADS_HDR.TXT    (contains the UADS header from the original ASCII data files)
../INST.TXT     (describes the OETP instrument)
../XCALIB_1.TXT (describes PVO ion instruments intercalibration)
../XCALIB_2.TXT (describes PVO ion instruments intercalibration)

The data are stored in 500 orbit ASCII data files. Each data file (.TAB) is
described by a detached PDS label file (.LBL) which describes some of the
physical properties of the data.  There is a single format file (.FMT) which
describes the columns of all of the data files.

The UADS header from the original ASCII files have been stripped out of each
data file (.TAB) and placed into the file UADS_HDR.TXT. This makes the files
easier to load into database applications. Individuals who desire proper UADS
files, can cancatenate the UADS header file (UADS_HDR.TXT) to the beginning of
the data files. This will recreate the original UADS ASCII files.

Columns in all data files:
=====================================================
name      type       units       description
-----------------------------------------------------
yeardoy   integer    N/A         Year/Day-of-year (1978304. is day 304, 1978)
msofday   integer    millsec     milliosecond-of-day
orbit     integer    N/A         PVO Orbit number
perisec   integer    second      Seconds after periapsis (negative before)
ele_temp  float      Kelvin      Electron temperature.
ele_den   float      cnts/cm^3   Log10(electron density)
sc_volts  float      Volts       S/C potential
 
Any data column whose value is greater than 1.0e30 is a missing data value.
