Notes. ν is the effective frequency, Δν denotes bandwidth, δ is declination in J2000 celestial coordinates, and σcal is the effective calibration uncertainty. The effective calibration uncertainty accounts for scale-calibration uncertainties due to incomplete beam characterization, which primarily affect the 408 MHz and 1.42 GHz maps. The FWHM and sky coverage values correspond to the native survey properties prior to convolution to 1°. † Frequencies excluded from fitting due to residual CO contamination.
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.
Initial download of the metrics may take a while.
