Notes.

^(a)

Offset positions are relative to the nominal center of the mosaic α_J2000 = 17^h45^m40^s, δ_J2000 = −29°00′28′′.

^(b)

Ratio of total integrated intensity of the CN and ¹³CN spectral features.

^(c)

Carbon isotopic ratio estimated from the opacity corrected CN/¹³CN integrated intensity ratio.

^(d)

Peak optical depth of the main hyperfine component.

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.
