      <Description>This data set contains the Cluster 2 STAFF-SA average power spectral density in the passband of the analogue receivers derived from the Automatic Gain Control signal.

This is measured in three large passbands with 1 s time resolution, for the axial component of the magnetic field, and the sums of the spin plane components of the magnetic and of the electric field.</Description>
