      <Description>Solar Orbiter, Level 2 Data, Energetic Particle Detector, Electron and Proton Telescope, Rates. 

              
            EPT  measures electrons and ions in the lower part of the energetic particle spectrum. It 
effectuates measurements in 4 different fields of view :

* Anti-Sunward Flow. Detector looks in the direction of the mean Parker spiral towards the Sun.
* Sunward Flow. Detector looks opposite to the Sun direction.
* Northward Flow. Detector looks towards the south ecliptic hemisphere.
* Southward Flow. Detector looks towards the north ecliptic hemisphere.

Parameter ID uses Detector looking directon.

Additionally, EPT has 2 channels that separate electrons and ions:
* Magnet channel. Uses a permanent magnet to deflect electrons. It measures protons with energies between 25 keV and 6.5 MeV and alpha particles up to 25 MeV.
* Foil channel. Equipped with a foil that absorbs ions, it measures electrons in the energy range 25–500 keV. Ions with energies above 400 keV can penetrate the foil, contaminating the electron measurements.

    <Caveats>Ions with energies around 500 keV can penetrate the foil and give a signal in the electron

           channel. In the presence of high ion flux, there could be a considerable contamination from ions in this product.</Caveats>
