Jackknife tests of the [C II] stacked spectrum for the BAL QSO sample. Each panel shows the stack of four out of five BAL quasars, with one excluded. The broad component remains visible across all tests, but its S/N decreases when excluding J0012, indicating that the result is not solely driven by a single source.
