TLDR
In this paper, the amplitude and pattern of the correlated noise from three techniques: angular averages of the covariance matrix, Monte Carlo simulations of two-point correlation functions and direct analysis of the DMR maps are mutually consistent.Citations

Karhunen-Loève Eigenvalue Problems in Cosmology: How Should We Tackle Large Data Sets?
TL;DR: In this article, a comprehensive discussion of methods for estimating cosmological parameters from large data sets, including the previously published techniques as special cases, is presented, and it is shown that both the problem of estimating several parameters jointly and the problem that not knowing the parameters a priori can be readily solved by adding an extra singular value decomposition step.

The 4 Year COBE Normalization and Large-Scale Structure
E. Bunn,Martin White +1 more
TL;DR: In this paper, the authors present an analysis of the 4-year data from the COBE DMR experiment and use a Karhunen-Loeve expansion of the pixel data to calculate the normalization and goodness of a range of models of structure formation.

TL;DR: In this paper, the authors applied Fourier analysis and power spectrum estimation of the cosmic microwave background anisotropy on an incompletely sampled sky developed by Gorski has been applied to the 4 yr COBE DMR 31.5, 53, and 90 GHz sky maps.

Two-Point Correlations in the COBE DMR Four-Year Anisotropy Maps

TL;DR: In this article, the two-point temperature correlation function is evaluated from the 4 yr COBE DMR microwave anisotropy maps, which is the Legendre transform of the angular power spectrum, and the data are statistically consistent from channel to channel and frequency to frequency.
