Correlated relations between p ₃₅ and p ₃₆ based on fitting the model to 5 individual data sets with different inputs. (A) Fitting to noise-free data sets. The 5 individual zero residual surfaces cross exactly at the true parameter point. It demonstrates that a zero residual surface from any data set will pass through the true parameter point and two data sets will be enough to determine p₃₅ and p₃₆. (B) Fitting to the data sets with 10% noise. The 5 individual nonzero residual surfaces cross near the true parameter point.
