In particular, the saturation effect is evident when comparing the distribution of EW/EWciv among different CIV groups. The CIVSA group exhibits smaller absolute values (with a standard deviation σ=0.213 for the best-fitting Gaussian component) compared to the CIV00 (σ=0.390) and CIVS0 (σ=0.357) groups. However, their Fcont/fcont distribution shows a similar wide range.
