Notes.

(a)

The two values correspond to the two Λ-components of the doublets; each one is the average of the two hyperfine transitions that make up a component.

(b)

GT and OT indicate “guaranteed time” and “open time”.

(c)

Identification number.

(d)

Number of spatial pixels used to generate the spectrum. In case of 1, the central pixel was used; in case of 3, the spectra from the three brightest spatial pixels were coadded. In all cases, the absolute fluxes were scaled to match the total flux as obtained by coadding the fluxes from the 25 pixels.

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.
