VLT/FORS2 spectropolarimetry of the CLAGN IRAS 23226-3843. The top-left figure shows the total flux spectrum (in arbitrary units). The most prominent telluric absorption lines are indicated in purple. The middle- and bottom-left figures present the Q/I and U/I normalized Stokes parameters. The top-right panel shows the polarized flux, that is the multiplication of the total flux with the polarization degree. The middle-right panel presents the debiased linear polarization degree while the bottom-right panel shows the polarization position angle. Except for the total flux panel, spectra were rebinned to 10 consecutive pixels. 1σ observational errors are indicated for each spectral bin, as well as the main, prominent, broad, and narrow emission lines.
