Spectropolarimetry with PEPSI at the LBT: accuracy vs. precision in magnetic field measurements
Abstract
We present the design of the new PEPSI spectropolarimeter to be installed at the Large Binocular Telescope (LBT) in Arizona to measure the full set of Stokes parameters in spectral lines and outline its precision and the accuracy limiting factors.
