Abstract:
This paper presents accurate homogeneous positions, velocities and
other pertinent properties for 460 newly discovered and 169 previously
known planetary nebulae (PNe) in the central 25-deg2 bar region of
the Large Magellanic Cloud (LMC). Candidate emission sources were
discovered using a deep, high-resolution Hα map of the LMC
obtained by median stacking a dozen 2h Hα exposures taken with
the UK Schmidt Telescope (UKST). Our spectroscopic follow-up of more
than 2000 compact (i.e. <20arcsec) Hα emission candidates
uncovered has tripled the number of PNe in this area. All of the 169
previously known PNe within this region have also been independently
recovered and included in this paper to create a homogeneous data set.
Of the newly discovered PNe, we classify 291 as 'true', 54 as 'likely'
and 115 as 'possible' based on the strength of photometric and
spectroscopic evidence. Radial velocities have been measured using
both weighted averaging of emission lines and cross-correlation
techniques against high-quality templates.
Description:
Having identified more than 2000 compact (diameter ≤20arcsec)
emission sources in the LMC, spectra were required to confirm emission
character and object types. A major spectral confirmation programme
was undertaken in 2004 November and December comprising five nights
using 2dF on the Anglo-Australian Telescope (AAT), seven nights using
the 1.9m at South African Astronomical Observatory (SAAO), three
nights using the FLAMES multi-object spectrograph on the ESO Very
Large Telescope (VLT) UT2 and seven nights using the 2.3m Australian
National University (ANU) telescope at the Siding Spring Observatory
(SSO). Finally, in 2005 February, we used 6dF on the UKST over three
half nights as a final high-dispersion multi-object follow-up. For the
purpose of this paper we are presenting results obtained from the AAT
and VLT with added confirmation from the 1.9m SAAO and 2.3m SSO
observations. In addition, the VLT spectra, which probe faint emission
lines in a subsample of the newly identified PNe, plus the UKST 6dF
high-resolution results, will be the subject of a further paper in
this series (Reid & Parker, in preparation).

Global notes:
Note (G1): The emission-line measurement (em) error (e_HRV) indicates the
weighted average difference in the objects' own internal velocities.
The cross-correlation (ccf) error (e_HRV2) is the averaged error
across all matching templates used to produce the velocity.
Note (G2): Comments have been abbreviated so that
c = circular (round),
e = elliptical (oval),
f = faint,
b = bright,
s = small,
p = point source objects which are small in the short red image,
ireg = irregular,
ds = double star,
bp = bipolar.
A comment of 'fading' refers to the outer appearance of the halo in Hα.
A comment of 'Hα only' means that the object is well defined
in Hα and only faintly visible in the short red (if at all).
The comment c∼e shows that while the object is circular, there appear
to be some interior components that tend to be elliptical.
