Crate light_curve_feature[−][src]
Expand description
light-curve-feature is a part of light-curve family that
implements extraction of numerous light curve features used in astrophysics.
use light_curve_feature::*; // Let's find amplitude and reduced Chi-squared of the light curve let fe = FeatureExtractor::<_, Feature<_>>::new(vec![Amplitude::default().into(), ReducedChi2::default().into()]); // Define light curve let time = [0.0, 1.0, 2.0, 3.0, 4.0]; let magn = [-1.0, 2.0, 1.0, 3.0, 4.5]; let weights = [5.0, 10.0, 2.0, 10.0, 5.0]; // inverse squared magnitude errors let mut ts = TimeSeries::new(&time, &magn, &weights); // Get results and print let result = fe.eval(&mut ts)?; let names = fe.get_names(); println!("{:?}", names.iter().zip(result.iter()).collect::<Vec<_>>());

Macros
Helper for static EvaluatorInfo creation
Helper for FeatureEvaluator implementations using time-series transformation. You must implement:
Structs
$\Delta t = \mathrm{duration} / (N - 1)$ is the mean time interval between observations
The engine that extracts features one by one
$\Delta t$ is the median time interval between observations
Direct periodogram executor
“Fast” (FFT-based) periodogram executor
$\Delta t$ is the $q$th quantile of time intervals between subsequent observations
