AB: The line strength of CN absorption has been observed to vary with the continuum intensity within sunspots, and the Doppler shift of the CN line at 1564.6nm has been shown to reveal fast Evershed flows in the penumbra. We examine several sunspots observed from 2002-2005 using intensity spectroscopy and spectropolarimetry to determine the line strength, plasma flow velocity, and the local magnetic field configuration as functions of position in these sunspots.
