[−][src]Struct light_curve_feature::PeriodogramPowerFft
"Fast" (FFT-based) periodogram executor
This algorithm spreads observer time series into uniform time grid using linear interpolation
and then uses FFT to obtain periodogram sums. This implementation returns estimation of
Lomb-Scargle periodogram that derives to the exact values while max_freq_factor grows.
Asymptotic time is $O(N \log N)$, it is faster then
PeriodogramPowerDirect even for $N \simge 10$.
Note that current implementation uses two-powered time grids and requires to estimate the best
FFT algorithm for each pair of grid size and working thread that can take several seconds,
especially for large grids.
The implementation is inspired by Numerical Recipes, Press et al., 1997, Section 13.8
