On 2012 September 19 & 20 (UT), a few brief imaging polarimetry measurements were made during another science program at the 6.5m MMT using SPOL and a narrow-band filter. The filter was kindly supplied by Daryl Willmarth (NOAO/KPNO) and we thank C. You and A. Zabludoff (Steward Obs.) for the telescope time.
The KP583 filter has a central wavelength of 4980 Å and a FWHM of nearly 60 Å. The transmission curve is given below.
