a) CMB-nulled map at 28.4 GHz, constructed using the ILC method (see text), where in this map, β = −3 emission is unchanged by construction; b) 408 MHz map (Remazeilles et al. 2015), strongly dominated by synchrotron emission; c) 545 GHz Planck map, strongly dominated by thermal dust emission; and d) Hα map (Dickinson et al. 2003). An asinh(I) colour scale is used for all images, where I is the intensity in the units indicated. The coordinate along the colour bar is linear in I near zero and becomes logarithmic (ln(2I)) at high intensity. All maps are at 1deg resolution.
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.
