        "Description": "The Neutral Particle Imager (NPI) of the ASPERA-3 package\nflown on Mars Express provides measurements of the integral ENA flux with no\nmass and energy resolution but with 5 deg x 11 deg angular resolution. The\nintrinsic field of view is 9 deg x 344 deg. The sensor utilizes a graphite surface\nto suppress the UV background. ENAs incident on the surface at a grazing angle of\n20 deg are reflected and/or cause ion sputtering. An MCP stack detects the reflected\nparticles and sputtered fragments with a discrete anode.",
