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.
