NGC 1346 observation taken with the VLT/FORS2 on August 12, 2024 (solid black line) and on September 4, 2024 (solid gray line). Top-left: Total flux spectra (in arbitrary units, but not renormalized). Middle- and bottom-left: q (=Q/I) and u (=U/I) normalized Stokes parameters. Top-right: Polarized fluxes, that is, the total flux multiplied by the polarization degree. Middle-right: De-biased linear polarization degrees. Bottom-right: Polarization position angles. Except for the total flux panel, spectra were re-binned to 100 consecutive pixels. Observational errors are indicated for each spectral bin, and the locations of Hα and Hβ emission lines, as well as the strongest atmospheric absorption bands (tellurics), are clearly indicated.
