Notes. Errors are derived with the Monte Carlo technique described in Sect. 3. Estimates below 3σ are in italics. σR is the standard deviation of the residuals Rν. σC is derived from σR after removing the contribution to the uncertainties due to instrumental noise in dust emission and H i maps. For and , the average over the fields is also reported (excluding low S/N values) together with its standard deviation.

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.
