A Model-based Technique for Ad Hoc Correction of Instrumental Polarization in Solar Spectropolarimetry
Sarah A. Jaeggli, Thomas A. Schad, Lucas A. Tarr +1
We present a new approach for correcting instrumental polarization by modeling the non-depolarizing effects of a complex series of optical elements to determine physically realizab…

Removal of Spectro-Polarimetric Fringes by 2D Pattern Recognition
R. Casini, P. G. Judge, T. A. Schad
We present a pattern-recognition based approach to the problem of removal of polarized fringes from spectro-polarimetric data. We demonstrate that 2D Principal Component Analysis c…
