      <Description>The Electron Spectrometer (ELS) of the ASPERA-4 package flown on Venus Express measures electrons in the energy range 0.01-20 keV.

The intrinsic field of view is 4 deg x 360 deg. The 360 deg aperture is 

divided into 16 sectors. The sensor is a standard top-hat electrostatic analyzer in a very compact design.</Description>
