The impact of the AUS effects, \({\varvec{a}}_{1}\) and \({\varvec{a}}_{2}\) , on the estimates of the set K and \({\Delta }_{C}\). The resulting estimates are AUS K and AUS \({{\varvec{\Delta}}}_{{\varvec{C}}}\). a The study of both AUS K and AUS \({{\varvec{\Delta}}}_{{\varvec{C}}}\) at various \({\varvec{a}}_{1}\) where \({\varvec{a}}_{2}\) = 0, K, \({{\varvec{\Delta}}}_{{\varvec{C}}}\) = 0.8; b the study of both AUS K and AUS \({\Delta }_{C}\) at various \({\varvec{a}}_{2}\) where \({\varvec{a}}_{1}\) = 0 and K, \({{\varvec{\Delta}}}_{{\varvec{C}}}\) = 0.8; c the study of AUS K at \({\varvec{a}}_{1}\)  = 0.09, \({\varvec{a}}_{2}\) = 0.01 – 0.09, \({\varvec{K}} = 0.8\) \({{\varvec{\Delta}}}_{{\varvec{C}}}\) = 0.8–0.01; d the study of AUS \({{\varvec{\Delta}}}_{{\varvec{C}}}\) with the same settings as c
