[][src]Struct light_curve_feature::StetsonK

pub struct StetsonK {}

Stetson $K$ coefficient described light curve shape

$$ \mathrm{Stetson}~K \equiv \frac{\sum_i\left|\frac{m_i - \langle m \rangle}{\delta_i}\right|}{\sqrt{N\,\chi^2}}, $$ where N is the number of observations, $\langle m \rangle$ is the mean magnitude and $\chi^2 = \sum_i\left(\frac{m_i - \langle m \rangle}{\delta_i}\right)^2$.

  • Depends on: magnitude, magnitude error
  • Minimum number of observations: 2
  • Number of features: 1
