 Current caveats:
 
 - Only the standard ``rates`` data products are supported (i.e., no ``burst`` or ``high cadence`` data).
-- Only electrons, protons and alpha particles are processed (i.e., for HET He3, He4, C, N, O, Fe are omitted at the moment).
-- For the old STEP data product (until Oct 22, 2021), the sectored data is not processed (i.e., only averaged data is supported) and electron data needs to be calculated manually.
