[−][src]Struct light_curve_feature::Periodogram
A number of features based on Lomb–Scargle periodogram
Periodogram $P(\omega)$ is an estimate of spectral density of unevenly time series.
Periodogram::new
's peaks
argument corresponds to a number of the most significant spectral
density peaks to return. For each peak its period and "signal to noise" ratio is returned.
$$ \mathrm{signal~to~noise~of~peak} \equiv \frac{P(\omega_\mathrm{peak}) - \langle P(\omega) \rangle}{\sigma_{P(\omega)}}. $$
Periodogram
can accept another dyn FeatureEvaluator
for feature extraction from periodogram
as it was time series without observation errors. You can even pass one Periodogram
to another
if you are crazy enough
- Depends on: time, magnitude
- Minimum number of observations: 2
- Number of features: $2 \times \mathrm{peaks}~+...$
