KPNO Narrow-band Filter 1226

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 NOAO/KPNO and we thank Y. Yang (KASI) and A. Zabludoff (Steward Obs.) for the telescope time.

The 1226 filter has a central wavelength of 5008 Å and a FWHM of 100 Å. The transmission curve for the filter is shown below.
