Notes. The integrated intensites for IRAS 16293A were obtained from integration over the line, while Gaussian fitting was used for the two other sources. Also listed are the obtained noise level (Trms), error on the integrated intensity σrms, and the total error σtot (combined error of the integrated intensity and the calibration).
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.
