Description
STEREO-B In-Situ Measurements of Particles and CME Transients (IMPACT) Solar Wind Electron Analyzer (SWEA) electron pitch angle distribution (PAD) in phase space density (in units of s^3/km^6) as a function of 12 pitch angle bins (centered at 7.5, 22.5, 37.5, 52.5, 67.5, 82.5, 97.5, 112.5, 127.5, 142.5, 157.5, 172.5 deg) and 10 variable energy bins (PAD values for energies < 50 eV are forced to fill values).
