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 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 Spectrometer ASPERA4_ELS spase://CDPP/Observatory/AMDA/VEX
