            <Description>This data set contains FIPS ( FIPS_NTP) ion number densities and temperatures,  
as well as the pressure calculated from their product.   
Quantities are calculated after sufficient time accumulation 
to allow meaningful interpretation. 
            
In this version of the dataset, many of these products are provided 
      in regions determined by hand-picked or modeled bow shock and 
      magnetopause boundaries.  Boundary picking was done by the MAG team at 
      a level of accuracy sufficient for the relatively low time resolution 
      FIPS data (10s - 60s).  Where these were not available, the model given 
      by Slavin et al. [Science, 2010] is used.

        <Caveats>
       The recovered density, temperature and pressure (NTP) product is  
      particularly sensitive to the region of Mercury's space environment in 
      which the data was taken. The reasons for this, based on validity of 
      required assumptions, are described in detail in the DDR SIS.  This 
      data is provided within the magnetosphere, where the assumptions are  
      likely to hold for averages of 1 minute or more.  It  is also 
      provided in the magnetosheath within a 45 degree cone angle of the X_MSO 
      axis.  The validity of the assumptions is much more variable here,  
      though they will often hold. USERS ARE STRONGLY CAUTIONED to read the  
      NTP section of the DDR SIS follow the recommendations for using these  
      quantities.
