v = speed, a = acceleration, = road gradient
METHODVerification of concentration measurements
5
Distribution of the measurement distribution of a controlled gas mixture with known relativeabundances.The binned data shows the measurements with the solid line showing a Normaldistribution derived from the measured data (solid) and theoretical (dashed).
