Finding charts are gzipped Postscript images. These are 1'x1' subframes
of the I-band reference frames centered on the star. White cross marks the
star. North is up and East to the left.
Figures related to the MCMC modeling of light curves using Kumar's model
are Portable Network Graphics (.png) images.
Any presentation of the scientific analysis or usage of the data from the
catalog of heartbeat stars in the Large Magellanic Cloud should include the appropriate
reference(s) to OGLE paper(s).
