The errors of computed transformation parameters and standard deviation of unit weight caused by different normal distributed random nosies N(0, \(\sigma_{0}^{2}\)). Each x axis value represents the different \(\sigma_{0}\) in meters. Each y axis value represents different accuracy index values: (a) error of rotation angle, in degrees. (b) Error of translation, in meters. (c) error of scale, in no unit. (d) \(\sigma\) in meters
