(left) D plasmas and (right) H plasmas. The line averaged density dependence of (a,b) the carbon impurity density, (c,d) the inverse gradient length of the carbon impurity density, and (e,f) the inverse gradient length of the electron density at \({r}_{{\rm{eff}}}/{a}_{99}=0.6\). (g,h) Scatter plot of the principal component score and eigen vectors of the original variables.
