AbsoluteSampleGasPressure is defined by IRDI as ABP560#001 which states “absolute pressure of sample gas inside a detection system”.
SampleTemperature is defined by IRDI as ABP575#001 which states “temperature of the sample at the point of measurement”.
TransmissionRatio is defined by IRDI as ABP582#001 which states “ratio of the value of a specified radiation quantity in the centre of a beam of specified radiation quality and under specified geometrical conditions after passage through a material to the value which would be present at the same position without this material in the beam”.
SignalNoiseRatio is defined by IRDI as ABP581#001 which states “linear ratio of the signal level to the noise level as measured under specified conditions”.
LaserTemperature is defined by IRDI as ABP583#001 which states “measured temperature of the element that defines the wavelength of a laser”.
SignalFitQuality is defined by IRDI as ABP580#001 which states “degree of correlation between the calculated and the measured absorption signal”.
The components of ITunableDiodeLaserSignalConditionSetType have additional references which are defined in Table 56.
