-----------------------------------------------------------------------
---------
Minimum Data Value -- The minimum value found in the column.
Maximum Data Value -- The maximum value found in the column.
Missng Data Value  -- The value that indicates missing data. This is
                      used to  indicate that an attempt was made to
                      determine the parameter value, but the attempt
                      was unsuccessful.
Unrel Data Value   -- The value that indicates unreliable data.  This 
                      is used to indicate an attempt was made to 
                      determine the parameter value, but the value was
                      deemed to be unreliable by the analysis
                      personnel.
Below Detect Limit -- The value that indicates parameter values below
                      the instruments detection limits.  This is used
                      to indicate that an attempt was made to determine
                      the parameter value, but the analysis personnel
                      determined that the parameter value was below the
                      detection limit of the instrumentation.
Data Not Cllctd    -- This value indicates that no attempt was made to 
                      determine the parameter value.  This usually 
                      indicates that BORIS combined several similar but 
                      not identical data sets into the same data base
                      table but this particular science team did not 
                      measure that parameter.

Blank -- Indicates that blank spaces are used to denote that type of
         value.
N/A   -- Indicates that the value is not applicable to the respective
         column.
None  -- Indicates that no values of that sort were found in the
         column.
