-
astroML.time_series.multiterm_periodogram(t, y, dy, omega, n_terms=3)[source]¶ Deprecated since version 0.4: The multiterm_periodogram function is deprecated and may be removed in a future version. Use astropy.stats.LombScargle instead.
Perform a multiterm periodogram at each omega
This calculates the chi2 for the best-fit least-squares solution for each frequency omega.
- Parameters
- tarray_like
sequence of times
- yarray_like
sequence of observations
- dyarray_like
sequence of observational errors
- omegafloat or array_like
frequencies at which to evaluate p(omega)
- Returns
- powerndarray
P = 1. - chi2 / chi2_0 where chi2_0 is the chi-square for a simple mean fit to the data
