Query: Variable stars in the bar of the Large Magellanic Cloud: the photometric
  catalogue   The catalogue of the Johnson-Cousins B,V and I light curves obtained for 162
variable stars (135 RR Lyrae, 4 candidate Anomalous Cepheids, 11 Classical
Cepheids, 11 eclipsing binaries and 1 delta Scuti star) in two areas close to
the bar of the Large Magellanic Cloud is presented along with coordinates,
finding charts, periods, epochs, amplitudes, and mean quantities (intensity-
and magnitude-averaged luminosities) of the variables with full coverage of the
light variations. A star by star comparison is made with MACHO and OGLE II
photometries based on both variable and constant stars in common, and the
transformation relationships to our photometry are provided. The pulsation
properties of the RR Lyrae stars in the sample are discussed in detail.
Parameters of the Fourier decomposition of the light curves are derived for the
fundamental mode RR Lyrae stars with complete and regular curves (29 stars).
They are used to estimate metallicities, absolute magnitudes, intrinsic (B-V)o
colours, and temperatures of the variable stars, according to Jurcsik and
Kovacs (1996), and Kovacs and Walker (2001) method. Quantities derived from the
Fourier parameters are compared with the corresponding observed quantities. In
particular, the "photometric" metallicities are compared with the spectroscopic
metal abundances derived by Gratton et al. (2004) from low resolution spectra
obtained with FORS at the Very Large Telescope.
