TLDR
A time-ordered method for map-making with one-horned experiments that has reasonable memory and CPU needs but can handle complex COBE-like scans paths and 1/f noise is given.Abstract:
CMB anisotropy experiments seeking to make maps with more pixels than the 6144 pixels used by the COBE DMR need to address the practical issues of the computer time and storage required to make maps. A simple, repetitive scan pattern reduces these requirements but leaves the experiment vulnerable to systematic errors and striping in the maps. In this paper I give a time-ordered method for map-making with one-horned experiments that has reasonable memory and CPU needs but can handle complex COBE-like scans paths and 1/f noise.read more

Cosmic confusion: degeneracies among cosmological parameters derived from measurements of microwave background anisotropies
George Efstathiou,J. R. Bond +1 more
TL;DR: In this article, the authors analyse degeneracies among cosmological parameters to illustrate some of the limitations inherent in CMB parameter estimation and show that small correlated errors in estimates of the CMB power spectrum at levels well below the cosmic variance limits (caused, for example, by Galactic foregrounds or scanning errors).
