Within this page, you may experiment with LMC Cepheid periods.
The data were obtained by the Optical Gravitational Lensing Experiment (OGLE) as described in the paper: "The Optical Gravitational Lensing Experiment. Cepheids in the Magellanic Clouds. IV. Catalog of Cepheids from the Large Magellanic Cloud."
In these interactive plots, I visualize data from the LMC_SC1 field. The complete dataset can be found at: OGLE LMC Cepheids Catalog .
