The comparison information, for a parameter, that is used to relate the values read at the monitor measurement point to the median values of the parameter in the cross-section. The field sensor used to measure the value of the parameter The value of the point reading at the monitor measurement point, for the parameter. The default units are defined by the Field Sensor. The median value for the parameter as computed from all of the parameter readings in the cross-section. The default units are defined by the Field Sensor. The coefficient value for the parameter when applied to the point value should correct the point value to the median of the cross-section readings.
