Comment on the "Excess ellipticity of hot and cold spots WMAP data?" by Berntsen, E. and Hansen, F.K

TL;DR

This paper critiques a recent study on the ellipticity of CMB anisotropies, highlighting overlooked literature and superficial analysis, emphasizing the need for more rigorous comparison of results.

Contribution

It provides a critical commentary on the methodology and conclusions of Berntsen and Hansen's analysis of CMB ellipticity.

Findings

Highlights missing relevant literature in previous studies

Points out superficial comparison of results and definitions

Emphasizes importance of noise and resolution considerations

Abstract

The recent paper by Berntsen and Hansen devoted to the analysis of elliptic-ity of anisotropies in CMB maps, distorts some statements of previous studies, misses relevant papers, along with superficial comparison of the results (in part of definitions, the role of noise, angular resolution, model parameters).
