The urine volume remaining in the measuring chamber of the AU when reference measurements were made did generally change between two successive measurements.
Subsequently, device and reference measurements were merged.
The results are compared to RTK-GPS reference measurements.
Since the reference measurements of the terrestrial values can vary greatly over time compared to the satellite measurements, the reference measurements of the terrestrial values must therefore be transformed to the reference measurements of the PSI method.
This step removes the observed offset between survey and reference measurements.
The reference measurements are performed shortly before or after the main measurement with the force.
The estimated speed profiles coincide qualitatively and quantitatively quite well with the reference measurements.
The estimation results are compared with both reference measurements and with a widely used crosstalk model.
The device has demonstrated good dosimetric capabilities when compared to reference measurements made with ionization chambers.
Exhaust emissions have been compared to reference measurements with diesel fuel and ethanol.
Since no reference measurements without photocatalytic material (prior to the application) exist, the interpretation of these results is rather difficult.
