ELFIN Data Tohban Report Tohban: Colin Wilkins (colinwilkins@ucla.edu) Date range: 2020-10-18 to 2020-10-27 Completeness: A fraction of ELA/ELB data still 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.

Intervals marked with 'TC' are test campaigns. Note to operators: Dates with *'s are likely of downlink priority. Multiple stars indicate a higher downlink priority. Please refer to the ELFIN overview plots for the specific time intervals of the features of interest.
