Rev., 71, 55, 1995).Each angular distribution was measured at a single electron energy. The energy was selected by applying a voltage between the electrostatic analyzer plates. The detector sampled 32 energies between 19 eV and 1238 eV, and during normal operation would sweep through these energies one at a time with approximately 12 second cadence.The instrument's 12 anodes are set in a vertical pattern in a plane that contains the spacecraft spin axis, spanning a field of view +/-28 degrees centered around the ecliptic (with uneven angular spacing between anodes). Wind's spin axis is set at a right angle with the ecliptic plane, allowing different azimuthal angles to be sampled as the spacecraft spins (3 sec spin period). These azimuthal bins have a fixed separation of 3.53 degrees. Each strahl (and antistrahl) distribution measured by the spacecraft consists of a 14x12 angular grid of electron counts, that was measured at a fixed energy during a single spacecraft spin. Counts are converted into physical units of f (v) (e.g., cm^-6s^3) in the standard fashion by accounting for the detector efficiency and geometric factor.The data set reported here contains: f_strahl, f_antistrahl, f_strahl_counts, f_antistrahl_counts, phi_strahl, phi_antistrahl, theta, energy. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ readme https://cdaweb.gsfc.nasa.gov/data/wind/swe/strahl0/readme_wind_strahl0_cdf.txt Wind STRAHL0 <_Note>URL also in all.xml, master.
