PIDF DATA QUALITY STRUCTURE

The PIDF Data Quality Structure provides labeling information and unit information for the UDF data quality flags. This structure is rarely used by applications other than to display the information within a GUI MENU.

The PIDF data quality structure has the generalized form:

struct DataQual {
   string name = "Entry";
   string short_name = "Entry";
   int    num_units = Entry;
   int    unit_number = Entry;
};

KEYWORD: name

KEYWORD: short_name

A short descriptive label for the measurement. This label is generally a decimated version of what is given in the name field.

This is a string field which if not included in the DQual structure is defaulted to a NULL.

KEYWORD: num_units

This is an int field which must be present in the structure.

KEYWORD: unit_number

The structure number of one of the PIDF unit definitions. This provides the information to take the raw measurement into one of the unit definitions provided for it. There are num_units instances of this field within the DataQual structure.

This is an int field of which at least one instance must be present in the structure.

EXAMPLES

EXAMPLE 1

pidf v2_IMHACCUM {
$*********************************************************************
    struct DataQual {
        string name = "Data Quality";                  $$ name
        string short_name = "dQ";                      $$ short name
        int num_units = 1;                             $$ no. of units
        int unit_number = 31;                          $$ unit numbers
    };
