Period Estimation for Quasi-Periodical Mira Variable Stars
https://shiyuanhe.github.io/varStar/
The subdirectory simulatedLightcurves
contains the simulated light curves and
supplementary table.
- [Simulated light curves] The file
simulated_lightcurves.tgz
contains 100,000 simulated light curves, generated following the procedure of our paper. Each light curve is stored in one file with three columns: MJD, I magnitude and uncertainty. The file name is based on the original OGLE variable ID from which it is generated (also listed in the next item). - [Mira variables] The file
supp_table.dat
is the table summarizing the relevant properties of OGLE LMC Miras from Soszynski et al. (2009) that were used to simulate the light curves: OGLE ID, main period and mean I & V magnitudes. It includes some extrapolated values of V for objects with missing data (suitably identified with a "*"). This table can be used to compare true versus derived periods and to generate Period-Luminosity relations.
