            <Description>Plasma density derived from individual spacecraft 
potential measurements on one illuminated probe. The derivation additionally 
uses low time resolution estimates of the plasma density from either RPCLAP or 
RPCMIP (changes over time).  The data here are derived from the LAP 
Vsc proxy known as U_SC which is available over all the mission, and 
are calibrated to MIP density values after 2014-12-31. Before this period the MIP 
density detections were scarce since densities usually were low, so the LAP 
sweep parameter N_E from ASW dataset was used for the calibration of U_SC to N_ED. 
This is a good calibration source precisely when MIP data are scarce, as low plasma density 
means low s/c potential, meaning that the otherwise very negative spacecraft potential here 
does not prevent plasma electrons from reaching the Langmuir probes.
