Notes. The full table with all the 1699 Hα emission-line stars is available at the CDS. A few lines are reproduced here only for guidance regarding format and content.

(a)

Kiso Hα catalogue from Wiramihardja et al. (1993).

(b)

Herbig & Bell (1988) catalogue.

(c)

Haro (1953) catalogue: Haro 4-1 to 4-255, Parsamian & Chavira (1982): Haro 4-256 to 4-495, Haro & Moreno (1953): Haro 5-1 to 5-98.

(d)

An asterisk means a star also listed in Szegedi-Elek et al. (2013).

(e)

Positions extracted from the 2MASS All-Sky Catalog.

(f)

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. A “+” indicates resolved spectra but unresolved DSS image.

(g)

The magnitudes mJ, mF, and mN are from the blue (IIIaJ emulsion), red (IIIaF emulsion), and infrared (IV-N emulsion) digitised sky surveys extracted from USNO-B catalogue or from GSC 2.2.

(h)

JHKs magnitudes extracted from the 2MASS All-Sky Catalog.

(i)

Notes to individual stars.
