| Abstract: |
The effects of limited resolution in two domains, spatial and temporal,
is briefly demonstrated through the use of synthetic data and
manipulation of emergent Stokes polarization spectra. The importance of
modeling the effects on incoming light is demonstrated, for averaging in
the temporal or spatial dimensions is an intensity-weighted function.
It is showed that when compared to direct binning of pure polarization
states or of later products such as derived magnetic field maps,
the evaluation of resolution effects based on these simpler methods can
be misleading. The general result is presented that limited-resolution
polarization spectra may generally have smaller amplitudes than their
constituent spectra, and sometimes drastically so; this may have implications
for signal/noise-driven integration-time estimates. |
