quv behavior of calibrated quv data sets or ϵ Aurigae observed with HiVIS on October 23rd 2013. The 4 main observing blocks at similar telescope pointings were combined after calibration to achieve high S/N of 5000 to 7600 in quv. The residual errors can be seen as a cluster of points around 0 with σ< 0.05%. The signal is largely qu with a linear polarization amplitude of 0.50% as expected from ESPaDOnS observations. The calibrated Stokes v amplitude is roughly 0.14%. This residual Stokes v corresponds to a 15° rotational calibration error between linear and circular polarization. This error is expected when combining all the uncertainties in our calibration demonstration derived over a 6 month time frame. See text for details.
