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.
