  While the observed nearly scale-invariant initial power spectrum is regarded
as one of the favorable evidence of the standard inflationary cosmology,
precision observations of the Cosmic Microwave Background (CMB) anisotropies
also suggest possible existence of nontrivial features such as those observed
around multipoles $\ell\sim120$ by WMAP. Here, we examine the Planck data and
investigate the effects of these features on the cosmological parameter
estimation performing the Markov-Chain Monte-Carlo (MCMC) analysis. We find
that the features exist in the Planck data at the same position as the case of
the WMAP data but they do not affect the cosmological parameter estimation
significantly.
