subframes of the I-band reference frames centered on the star. White cross
marks the star. North is up and East to the left.

Object OGLE-GD-CEP-0013 was spectroscopically confirmed
to be a Classical Cepheid (Pietrukowicz et al. 2015, AcA, 65, 63;
arXiv:1503.03499). It probably pulsates in the first overtone
rather than fundamental mode.
Any presentation of the scientific analysis or usage of the data from the
OGLE catalog of variable stars should include appropriate references
