TL;DR: In this article, the performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative cooling and three active mechanical coolers.

TL;DR: In this paper, the test results of the qualification model (QM) of the LFI instrument, which is being developed as part of the ESA Planck satellite, are presented, in particular the calibration plan which has defined the main requirements of the radiometric tests and of the experimental setups.

TL;DR: In this paper, the authors describe a software application which has been purposely developed and used during the RCA test campaign to carry out both near-realtime on-line data analysis and data storage (in FITS format) of the raw output from the radiometric chains.

TL;DR: In this paper, the authors present an example of procedures, test development and analysis successfully applied to a key software project of an ESA mission, where the on-board and ground processing are viewed as a single pipeline, and demonstrate that the scientific and housekeeping processing of the Planck-LFI raw data is correct and meets the project requirements.

TL;DR: A new formulation of the Conviqt convolution algorithm in terms of spin harmonics is introduced, and this is applied to the problem of sidelobe correction for B eyond P lanck, the first end-to-end Bayesian Gibbs sampling framework for CMB analysis.
