We classified the 260 CIV BALs selected from a multi-observational quasar catalog provided by Filiz Ak et al. (2014) into six groups (CIV00, CIVs0, CIVS0, CIVsa, CIVSa, and CIVSA) based on the presence of SiIV and/or AlIIII BALs/mini-BALs at the corresponding BAL regions. We then analyzed the correlation between the fractional EW variation of the BALs and the fractional variation of the continuum for each group.

Our results show anti-correlations between the fractional flux variations of the continuum and fractional EW variations for the CIV BALs without AlIII BALs at corresponding velocities. This provides evidence for the widespread effects of ionizing continuum variability on the variation of HiBALs. However, when the CIV BAL is accompanied by AlIII BAL/mini-BAL, no significant correlation is detected. The absence of such a correlation does not rule out the possibility that the variations in these low-ionization lines are caused by ionizing continuum variability. Instead, it can be attributed to the effects of BAL saturation, variable shielding gas, and the ionization state of the outflow to some extent.

In particular, the saturation effect is reflected in the comparison of the distribution of the CIVSA group (with a standard deviation σ=0.213 for the best-fitting Gaussian component), which tends to have smaller absolute values than the CIV00 (σ=0.390) and CIVS0 (σ=0.357) groups. However, their distributions still show comparable wide ranges.

In summary, our statistical analysis based on the fractional variation of BALs and the continuum reveals the widespread effects of ionizing continuum variability on the variation of outflow absorption across a wide range of ionization levels and viewing inclinations
