Notes. The full table with all the 398 Hα emission-line stars is available at the CDS. A few lines are reproduced here only for guidance regarding format and content.

^(a)

The numbers fall into two groups (1835−2123 and 2706−2769).

^(b)

Kiso: Wiramihardja et al. (1986); SS: Stephenson & Sanduleak (1977); LkHα: Herbig (1960); OSP: Ogura et al. (2002).

^(c)

Positions extracted from the 2MASS All-Sky Catalogue.

^(d)

The Hα strength is defined so 1 is weak emission against a strong continuum and 5 is strong emission against a weak or invisible continuum. Hyphenated values may represent either variability and/or uncertainty in the estimate.

^(e)

Broad band magnitudes from Gaia.

^(f)

JHK_s magnitudes extracted from the 2MASS All-Sky Catalogue.

^(g)

Magnitudes from AllWISE.

^(h)

Distances and errors extracted from Gaia-DR2.

⁽ⁱ⁾

Stars with uncertain photometry in one or several bands are flagged with a “:”. Those stars are not considered in discussions or plots regarding photometry.

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.
