# NN_Periodogram Find the periods of variable stars in any survey's light curves, and tell real periods from harmonics and aliases, with a small neural network that runs on a GPU or a CPU. ```python import nn_periodogram as nnp p = nnp.periodogram(time, mag, err) # find the period p.best_period, p.best_fap, p.peaks nnp.check_period(time, mag, 1.0155, err) # is a known period right, 2P, P/2 or an alias? nnp.fap(time, mag, [0.5077, 1.0155], err) # false-alarm probability of given periods ``` ```{toctree} :maxdepth: 2 usage devices models api citing ```
