Abstract
Full Stokes polarimetry is obtained using the National Solar Observato ry Vacuum Tower Telescope at Sacramento Peak while observing the magne tically sensitive infrared FeI line at wavelength of 1.56 mu. A techni que is described which makes use of the high magnetic resolution in th is spectral range to remove instrumental polarization from observed St okes Q, U, and V line profiles.
