Rotation Periods for Stars in Open Cluster NGC 6819 From Kepler IRIS Light Curves

Samples from the gyrochrone fitting with a Mixture Model from the paper Rotation Periods for Stars in Open Cluster NGC 6819 From Kepler IRIS Light Curves from Sagynbayeva, Colman, & Farr 2025.'gyrochrone_samples.nc' is the trace with the posterior samples from our mixture model fit of the gyrochrone. 'mix_model.ipynb' contains the mixture model and the code for Figure 6 of the paper (written in Julia). 'period_GPmodel_NGC6819.py' contains the Gaussian Process model for the period determination (written with PyMC, but then later sampled with emcee). 'final_catalog_NGC6819.csv' contains the catalog of our inferred periods for NGC 6819 with columns: KIC_ID, best_model, best_model_logp, gp_period_median, gp_period_lower, gp_period_upper, literature_period (if exists), model_f0_1_2_logp, model_f0_2_4_logp, model_f0_4_8_logp, model_f0_8_16_logp, model_f0_16_32_logp, Teff_K,log_g, Radius_Rsun, Source, sigma_significance, contam.
