Description:
The present catalogue presents a list of 3216 stars mostly earlier
than type F which have shown emission features and specifically one or
more lines of the Balmer series in emission. It is a compilation and
rearrangement of the following lists:
* the Catalogue and Bibliography of Stars of Classes B and A whose spectra
have bright H lines by P. Merrill and C. Burwell,
* the lists of Haro and his associates at Tonantzintla,
* the catalogues of Luminous Stars in the Northern Milky Way, Vols. I to VI
published by the astronomers of the Hamburger Sternwarte and the Warner
and Swasey Observatoryy (III/76)
* shorter lists of emission stars published by Parenago, Bidelman and
McCarthy and Treanor have also been included.
The present catalogue has a simple aim: to assist the astronomer in
finding from a vast array of articles in the literature whether the
star under investigation has been known to show emission features in
the earlier major surveys of emission stars of early type carried out
at the Mount Wilson, Tonantzila, Hamburg and Warner-Swasey Observatories.
The catalogue includes the star identification, Durchmusterung
identification, source catalog, RA and Dec, Galactic latitude and
longitude, apparent magnitude, spectral classification and remarks.

Note (1): the symbols are:
M = same star is listed in multiple sources;
first source only is given in "ref" column
(see Table three in the original publication
for additional designations and references)
* = uncertain identification of stars in different sources
Note (2):
The rubric that was adopted in the Henry Draper Catalogue of denoting
declinations different from the declination of the 1900.0 epoch has
been followed in the present catalogue. For example, Vatican No. 7
which is the equivalent of Star No. 3 in the A catalogue (i.e.
Merrill and Burwell: Mount Wilson Catalogue, Star No. 3) is indicated
as BD -2829 to indicate, by reference to DE (60deg, 4arcmin), that
this star is BD +59 2829. Thus, the "-" denotes in this catalogue
(just as the italics did in the Henry Draper Catalogue) the fact of
the change in declination of the star between the 1855 epoch of the
Bonner Durchmusterung and the 1900 epoch adopted for all the stars
in the present listing.
Note (3): The source catalogues where the emission features is noted.
Code letters are indicated in table1.dat;
for multiple sources see Table Three in the publication.
* in a few cases stars in the Luminous Star lists were cited in more
than one catalogue of this series. The LS serial number listed in
parentheses corresponds to the earlier catalogue.
* the minus (-) indicates a difference in zone, as in Note (2) above
Note (4):
Apparent magnitudes as found in the original source catalogue. These
are of necessity a mixture of visual magnitudes taken from various
Durchmusterungs, photographic magnitudes interpolated from Selected
Areas, open cluster sequences and in some cases derived directly by
the various authors from visual inspection of spectrum plates. Hence
very large differences in the published magnitudes for the same star
are quite common even apart from the known or suspected variability of
many of these stars. The flag (n_mag) means:
V = star is variable
* = uncertain magnitude
X = magnitude from another source than "ref"
Note (5): The letter "e" is omitted since presumably all stars listed have
shown emission characteristics. The remarks are:
C = refers to the continuous emission feature
L = refers to the line emission beginning at H beta
* = denotes uncertainty in the emission feature observed

History:
* The catalogue was prepared by the authors F.C. Bertiau and
M.F. McCarthy on punched cards ca 1970 and forwarded to CDS
(see 1971BICDS...1...23. 1971BICDS...1...23.)
* 07-May-1996: standardisation of the catalog by Julie Anne Watko
[SSDOO/ADC]. She added the table1.dat
* 26-Jan-2016: Parenago designations moved to the identification column
as in the printed paper. The documentation was revised, and bibcodes
added at CDS (Francois Ochsenbein)
