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 measurement (0.5% DE/E, 20.3 eV to 25.85 eV) using the ESA and RPA combined.” <_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/ https://doi.org/10.1007/s11214-022-00908-0 https://doi.org/10.1007/s11214-022-00908-0 Collinson, G., Glocer, A., Pfaff, R. et al.
