  In recent years, there have been a large number of studies which support
violation of statistical isotropy. Meanwhile, there are some studies which also
found inconsistency. We use the power tensor method defined earlier in the
literature to study the new CMBR data. The orientation of these three
orthogonal vectors, as well as the power associated with each vector, contains
information about possible violation of statistical isotropy. This information
is encoded in two entropy measures, the power-entropy and alignment- entropy.
We apply this method to WMAP 9-year and PLANCK data. Here, we also revisit the
statistics to test high-l anomaly reported in our earlier paper and find that
the high degree of isotropy seen in earlier WMAP 5-year data is absent in the
revised WMAP 9-year data.
