Notes. (*) For a linear fit E(B − V) = a + b ∗ EW. a is in magnitude units (mag), b is in mag/mÅ (**). Average equivalent width per reddening unit (mÅ/mag). (1) excluding HD 179029. (2) excluding ρOph and HD 179029. (3) excluding ρOph, HD 29647, HD 37061, θ1OriC (£) excluding ρOph, HD 29647, HD 37061, θ1OriC, and restricted to stars with EW ≤ 230 mÅ. (4) excluding ρOph, HD 29647, HD 37061, θ1OriC, and restricted to stars with EW ≤ 600 mÅ.
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.
