STANDEVI Relative uncertainty on the data point estimated from a noise model. The relative uncertainty (one standard deviation) on data is given as a factor. The total relative uncertainty on the data point is calculated when querying data as the square root of the square sum of the uncertainty given by the noise model (PacesDat.StanDevi) and the uniform uncertainty (PacesHea.StanDeviUn). The absolute uncertainty (length of error bar) on the data point is found by multiplying and dividing the data value by the factor, respectively. NUMBER 4 3
TXCURRENT Transmitted current in A NUMBER 6 4
TIC Tic-number NUMBER 8 0
