Any provided meta-data values specified in the attributes override any specified generic characteristics such as defined for a specific measurement in the MeasurementSiteTable. Indication of whether the value is deemed to be erroneous by the supplier (true = erroneous). If not present, the data value is assumed to be ok. This may be used when automatic fault detection information relating to sensors is available. The reason why the value is deemed to be erroneous by the supplier. The extent to which the value is expected to be free from error, measured as a percentage of the data value. 100% means fully accurate. Method of computation which has been used to compute this data value. The number of inputs detected but not completed during the sampling or measurement period; e.g. vehicles detected entering but not exiting the detection zone. The number of input values used in the sampling or measurement period to determine the data value. Coefficient required when a moving average is computed to give specific weights to the former average and the new data. A typical formula is, F being the smoothing factor: New average = (old average) F + (new data) (1 - F). The standard deviation of the sample of input values from which this value was derived, measured in the units of the data value. A measure of data quality assigned to the value by the supplier. 100% equates to ideal/perfect quality.
