Query: A numerical study of observational systematic errors in lensing analysis
  of CMB polarization   Impacts of observational systematic errors on the lensing analysis of the
cosmic microwave background (CMB) polarization are investigated by numerical
simulations. We model errors of gain, angle, and pointing in observation of the
CMB polarization and simulate polarization fields modulated by the errors. We
discuss the response of systematics-induced $B$-modes to amplitude and spatial
scale of the imposed errors and show that the results of the lensing
reconstruction and delensing analysis behave according to it. It is observed
that error levels expected in the near future lead to no significant
degradation in delensing efficiency.
