      abstract     = {Fully polarized neutron reflectometry and grazing incidence
                      small angle neutron scattering are effective methods to
                      explore magnetic structures on the nm to μm length scales.
                      This paper is an outline of how to fully correct for the
                      polarization analysis (PA) inefficiencies of such an
                      instrument and to determine the error contributions of the
                      neutron polarizer and analyzer. This discussion considers
                      the exact case of the polarization analysis instrumentation
                      used on the MARIA neutron reflectometer at the MLZ or for a
                      general polarized neutron scattering instrument using at
                      least one 3He neutron spin filter that has the capability
                      for adiabatic fast passage nuclear magnetic resonance
                      flipping of the 3He polarization. This paper will work to
                      build a conceptual understanding of how the inefficiencies
                      of neutron polarization elements affect measured data in
                      order to stress and encourage the application of PA
                      corrections and to help perform successful measurements.
                      Then, using data from a fully polarized neutron
                      reflectometer test measurement we show how it is possible to
                      recover signals on the order of, or even smaller than, the
                      inefficiencies, or bleed-through, of the neutron
                      polarization devices used.},
