Query: Testing statistical Isotropy in Cosmic Microwave Background Polarization
  maps   We apply our symmetry based Power tensor technique to test conformity of
PLANCK Polarization maps with statistical isotropy. On a wide range of angular
scales (l=40-150), our preliminary analysis detects many statistically
anisotropic multipoles in foreground cleaned full sky PLANCK polarization maps
viz., COMMANDER and NILC. We also study the effect of residual foregrounds that
may still be present in the galactic plane using both common UPB77 polarization
mask, as well as the individual component separation method specific
polarization masks. However some of the statistically anisotropic modes still
persist, albeit significantly in NILC map. We further probed the data for any
coherent alignments across multipoles in several bins from the chosen multipole
range.
