Abstract:
We present a catalogue with coordinates and photometric data of 2446
Be star candidates in the Large Magellanic Cloud (LMC), based on a
search of the OGLE II data base. The I-band light curves of these
stars show outbursts in 24% of the sample (Type-1 stars), high and low
states in 10%, periodic variations in 6% (Type-3 stars), and
stochastic variations in 60% of the cases. We report on the result of
the statistical study of light curves of Type-1 and Type-3 stars in
the LMC, and the comparison with the previously reported results of
the Small Magellanic Cloud (SMC) sample.

Note (1): Type of Be-stars as follows:
1 = Type-1 stars, showing outbursts
1/2 = Type-1 stars with luminosity jumps in their light curves
2 = Type-2 stars, showing sudden luminosity jumps
(i.e. high and low states)
3 = Type-3 stars, showing periodic or near-periodic variations
4 = Type-4 stars, showing light curves similar to Galactic Be stars.
Note (2): Abbreviations are:
"ART" means after removing trend;
"VA" means variable amplitude;
"DPV" means double periodic variable;
"MA" means multiple aliases;
"doubtful" means that star could be a Type-1 or Type-3 star.
