astroML.time_series.ACF_scargle(t, y, dy, n_omega=1024, omega_max=100)[source]¶ Compute the Auto-correlation function via Scargle’s method
- Parameters
- tarray_like
times of observation. Assumed to be in increasing order.
- yarray_like
values of each observation. Should be same shape as t
- dyfloat or array_like
errors in each observation.
- n_omegaint (optional)
number of angular frequencies at which to evaluate the periodogram default is 2^10
- omega_maxfloat (optional)
maximum value of omega at which to evaluate the periodogram default is 100
- Returns
- ACF, tndarrays
The auto-correlation function and associated times
