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.

    Abstract:
        We present new, accurate positions, spectral classifications, radial
        and rotational velocities, H{alpha} fluxes, equivalent widths and B,
        V, I, R magnitudes for 579 hot emission-line stars (classes B0-F9) in
        the Large Magellanic Cloud (LMC) which include 469 new discoveries.
        Candidate emission-line stars were discovered using a deep,
        high-resolution H{alpha} map of the central 25 degree2 of the LMC
        obtained by median stacking a dozen 2h H{alpha} exposures taken with
        the UK Schmidt Telescope (UKST). Spectroscopic follow-up observations
        on the Anglo-Australian Telescope, the UKST, the Very Large Telescope,
        the South African Astronomical Observatory 1.9m and the 2.3-m
        telescope at Siding Spring Observatory have established the identity
        of these faint sources down to magnitude Requiv~23 for H{alpha}
        (4.5x10-17ergs/cm2/s/Å).

    Description:
        Over a period of three years, from 1997, a series of repeated
        narrow-band H{alpha} and matching broad-band short red (SR) exposures
        of the central LMC field were taken in order to produce a deep
        H{alpha} and SR image with a 1mag depth gain over a single image
        frame. The 12 highest quality and well-matched UK Schmidt Telescope
        (UKST) 2-h H{alpha} exposures and six 15-min equivalent SR-band
        exposures were selected. From these exposures, deep, homogeneous,
        narrow-band H{alpha} and matching broad-band SR maps of the entire
        central 25 degree2 region of the LMC were constructed.
