Empirically estimated electron lifetimes in the Earth's radiation belts: 1. Observations

These data are provided as supporting information for the manuscript \"Empirically estimated electron lifetimes in the Earth's radiation belts: 1. Observations\" by Claudepierre et al. These data include electron flux measurements in the Earth's radiation belt obtained with the MagEIS instrument on the NASA Van Allen Probe B satellite, along with the empirical decay timescale estimates described in the manuscript. The contents of the data files are described in greater detail in the corresponding \"readme\" files.
