ELFIN Data Tohban Report Tohban: Colin Wilkins (colinwilkins@ucla.edu) Date range: 2020-10-15 to 2020-10-21 Completeness: A significant fraction of ELA/ELB data has not been downlinked for these dates due to ground station problems. Report to be updated in the future. Special/misc. notes: ELB data between 2020-10-18 07:35:06.796863 and 2020-10-19 08:29:55.534000 is using a special test set of detector thresholds to maximally eliminate noise. These impact count rates in each energy channel and effectively cut off the lowest energy channels.
