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.
