Supplement to: Electron energy partition across interplanetary shocks: III. Analysis

<strong>Quick Summary:</strong> The PDF file herein provides additional example superposed epoch analysis (SEA) plots in addition to reference tables of the upstream values used to normalize the SEA data in this file and those in the paper this supplement supports. This is a supplement to Part 3 of a three-part study of the electron velocity distribution functions (VDFs) observed near interplanetary (IP) shocks by the <em>Wind</em> spacecraft. Paper I [<em>Wilson et al.</em>, 2019a] introduced the methodology and data products [<em>Wilson et al.</em>, 2019c] for fitting the electron VDFs to the sum of three model functions. Paper II [<em>Wilson et al.</em>, 2019b] presents the statistics of the fit parameters produced and provided in the data products from Paper I. Paper III presents and summarizes the analysis of the fit parameters. The papers share the title <strong><em>Electron energy partition across interplanetary shocks</em></strong>. <strong><em>Wind</em> Spacecraft:</strong> The <em>Wind</em> spacecraft (https://wind.nasa.gov) was launched on November 1, 1994 and currently orbits the first Lagrange point between the Earth and sun. It holds a suite of instruments from gamma ray detectors to quasi-static magnetic field instruments, <strong>B</strong>_o. The instruments used in this study and these datasets are the fluxgate magnetometer (MFI), the radio receivers (WAVES), ion Faraday cups (SWE), and the electron and ion electrostatic analyzers (3DP). The MFI measures 3-vector <strong>B</strong>_o at ~11 samples per second (sps); the SWE measures reduced VDFs of the thermal proton and alpha-particle populations from which velocity moments are derived and used herein; WAVES observes electromagnetic radiation from ~4 kHz to &gt;12 MHz which provides an observation of the upper hybrid line (also called the plasma line) used to define the total electron density; and 3DP observes full 4π steradian VDFs of electrons and ions from a few eV to ~30 keV which provide both ion velocity moments and the electron VDFs modeled herein. <strong>PDF
