      <Description>The Mercury Plasma Particle Experiment (MPPE) suite is a comprehensive instrument package to observe the solar wind at 
      Mercury’s position and the whole plasma environment at Mercury. It consists of seven sensors including Mercury Electron Analyzers 
      (MEA1 and MEA2), Mercury Ion Analyzer (MIA), Mass Spectrum Analyzer (MSA), High-Energy Particle instrument for electron (HEP-e), 
      High-Energy Particle instrument for ion (HEP-i), and Energetic Neutrals Analyzer (ENA). 
      These sensors measure plasma, high-energy particles and energetic neutral atoms with sufficiently high time resolution, 
      wide energy and dynamic range, wide angle coverage, and high mass resolution.
      
      Mercury Ion Analyzer (MIA), one of MPPE sensors onboard Mio, measures both the 3D distribution function of solar wind ions 
      around Mercury and the planet’s magnetospheric ions to understand the structure and plasma dynamics of Mercury’s magnetosphere, 
      Mercury-solar wind interaction, atmospheric abundances, structures, and generation/loss processes, and the solar wind at Mercury’s 
      position. MIA consists of a top-hat type electrostatic analyzer with toroidal deflectors, microchannel plates (MCPs), 
      high-voltage power supplies. The analyzer selects energies of ions from 10 eV/q up to 30 keV/q depending on the operation modes with 64 

      spin angle sectors.
      
      ==== Data Procucts: ====
      
      MIA LEVEL1 CDF files consist of three sub-levels:
      * l1: Raw data with minimal processing for an archive purpose. Not useful for most users. Logarithmically compressed counts of E-t products are not uncompressed. Onboard velocity moments are stored as CDF_UNIT2 and are not converted to physical units.
      * l1p: Data preliminarily converted to physical units. Background counts are not subtracted. May be used for preliminary analysis with great caution.
      * l1p2: Calibrated data in physical units. Background counts are subtracted. Will be converted to LEVEL2 data with full metadata by Nagoya Mio Science Center.</Description>
