A few imaging polarimetry measurements have been obtained during another science program at the 6.5m MMT using SPOL and a narrow-band filter. The filter was kindly supplied by Y. Yang (KASI) and we thank Dr. Yang and A. Zabludoff (Steward Obs.) for the telescope time.
The NB403 filter has a central wavelength of 4030 Å and a FWHM of 100 Å. The transmission curve for the filter is shown below.
