ENDURANCE_L1B_PES

Description

The Endurance PES instrument was comprised of 8 boom-mounted Dual Electrostatic
Analyzer (DESA) sensors, and a main electronics box (MEB). Each DESA sensor had
two look directions; A-side (looking down to Earth from launch to pitch-over
maneuver, and then up to space until loss of signal (LOS)); and B-side (looking
up to space from launch to pitch-over, and then down to Earth until loss of
signal (LOS)). The sensors were synchronized by the MEB and cross-calibrated to
look at approximately the same energy at the same time. A PES sweep consisted of
81 different steps and took 10 seconds. At each step, a voltage could be applied
to the Electrostatic Analyzer (ESA) and/or the Retarding Potential Analyzer
(RPA). Of these 81 steps; 3 (0, 1, 44) were used to take background counts with
the ESA grounded, and to fire the SLP; 34 (2:9, 33, 56:80) were used to collect
the standard resolution data measurement (15% DE/E, 10eV to 1keV) using the ESA
alone; and 44 (10:32, 34:43, 45:55) were used to collect the high-resolution

ENDURANCE_L2_SLP

Description

The Endurance SLP was a needle probe mounted on the forward Fo’c’sle of the
spacecraft. It measured thermal plasma density, electron temperature, the
potential difference between the spacecraft and ambient plasma (plasma
potential) and the relative potential of the spacecraft. SLP performed an active
(20ms) sweep once every 5 seconds, wherein a sweeping +/- 5V voltage was applied
to the needle. The data products here were derived from the I-V curves and
intercalibrated with EISCAT Radar and the PES instrument.

Caveats

 This file has particularly bad background problems due to intense
 radiation belts from ~08:00-10:00 UT.
 This file contains both onboard calculated moments (labeled 
 "raw" with an "*" in the name) and moments calculated on 
 the ground from 3D distributions (labeled "final").
 Quantitative analysis should be done with the "final" moments.  
 The raw data should only be used qualitatively for identifying
 regions and temporal variations.  It has large errors, particularly
 in Vz in spacecraft coordinates.
 O+ and He+ data should not be used in the magnetosheath or at low
 L-values, due to background problems.
 Contact the LI at Lynn.Kistler@unh.edu if the data you need
 is not available on-line.
