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. spase://SMWG/Person/Stas.Barabash PrincipalInvestigator spase://CNES/Person/Andrew.J.Coates GeneralContact ESA Venus-Express ASPERA-4 description http://sci.esa.int/venus-express/33964-instruments/?fbodylongid=1442 PSA ASPERA web page ftp://psa.esac.esa.int/pub/mirror/VENUS-EXPRESS/ASPERA4/VEX-V-SW-ASPERA-2-ELS-V1.0/CATALOG/INST.CAT ElectrostaticAnalyser ASPERA4 spase://CNES/Observatory/CDPP-AMDA/VEX
