J/A+AS/102/451 Emission-line stars and PNe in the SMC (Meyssonnier+ 1993)

Description:
An objective-prism survey of the Small Magellanic Cloud (SMC) has been
performed through an H-{alpha} + [NII] interference filter, using the
90cm Curtis Schmidt telescope of Cerro Tololo. 1898 emission-line
objects have been detected in the main body of this galaxy, almost
quadrupling the number of those found in the same region by the
previous objective-prism surveys. Among these objects are newly
discovered planetary nebulae, compact HII regions and late-type stars.
Continuum intensity, as well as the shape and relative strength of the
H-{alpha} emission-line have been estimated; coordinates,
cross-identifications for the listed objects are provided.
The original paper contains in addition finding charts.

Note (2): The three digits describe the spectrum as it appears
on our deepest objective-prism plate:
(a) relative intensity of the continuum quoted from 1 (faint) to 5
(overexposed), "2-3" pointing out an optimum exposure; the
additional symbol "T" denotes that a trace of continuum is
barely visible above the sky background on our plate, while
intensity "0" indicates that the related object does not show
any continuous spectrum underlying the emission-lines,
(b) relative strength of the Halpha emission-line estimated on
a scale from 1 to 5, in which 1 represents a very weak line and 5 a
very strong line,
(c) estimate of the Halpha emission-line feature, where "1"
denotes a sharp line, "2" a line appreciably widened and "3"
a line which is diffuse to very diffuse.
Note (3): Code for the nature of the objects:
(1) H II region or filaments
(2) supernova remnant
(3) bubble or loop
(4) compact or small HII region
(5) PN or PN candidate (:)
(6) VLE or VLE candidate (:)
(7) Wolf-Rayet star
(8) Peculiar Halpha emission-line stars with FeII and [FeII] emission
Note (4): The first word (followed by one or more blanks) contains
cross-identifications separated by commas, in chronological order,
given by a letter abbreviation followed by the number assigned by
the respective authors who identified the object. Cluster information
on the star location in connection with the SMC cluster system; a
given star may lie either within a cluster or in its nearby
surrounding field but that, of course, does not imply cluster
membership.

(*) Note that Lindsay (1961) did not provide finding charts for several
emission objects listed in his catalogue, thus their identification is
possible only with the help of their coordinates. When Lindsay's
coordinates for an object do not match ours adequately, the Lindsay
cross-identification "L" number is followed by a colon.
Letter abbreviation for author who previously found the object:

Note (5): The acronym [MA93] is also found in the literature.
The stars are numbered according to increasing right ascension.
Note (6): the colons following the number indicates that the Halpha
emission-line nature of the object is doubtful or very doubtful,
mainly due to its severe faintness or because it is a late-type star.
Note (7): the relative intensity of the Halpha line is obtained
from the measurement of the optical density (0 - 5) of the
emission-line-peak on the digitized image of our 4-hour
exposure objective-prism plate.
