Notes. From left to right: Experiment name, frequency, angular resolution, sky fraction, and instrument noise (, in polarisation). The standard deviations (σ) in mJy give the contributions of instrument noise, radio and dusty (IR) galaxies, CIB clustering, and CMB, to the total noise (σtot) when a point-source flux is measured (in intensity). They are corrected for the flux lost by the aperture photometry procedure. Slim is the point-source flux limit (computed from σtot using Eq. (43)). SNradio and SNIR are the radio and dusty galaxy shot noises, respectively, corresponding to a flux cut equal to Slim.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
