Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

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 (3): Code for the nature of the objects as follows: 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 H{alpha} 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.

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: B = Bruck 1976 (1976ORROE...1....1B) H = Hodge 1986 (1986PASP...98.1113H) HW = Hodge & Wright 1974 (1974AJ.....79..858H) K = Kron 1956 (1956PASP...68..125K) Ln = Lindsay 1958 (1961AJ.....66..169L) NGC = Dreyer 1888 (cat. VII/1) 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 H{alpha} 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 H{alpha} 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.
