vector_cum_gamma_spline

zdm.energetics.vector_cum_gamma_spline(Eth: ndarray, *params)

Cumulative gamma-function luminosity function using spline interpolation.

Fast version of vector_cum_gamma that uses pre-computed spline interpolators. This is the recommended function for grid calculations.

Parameters:

• Eth (ndarray) – Energy threshold values in erg.

• *params (tuple) – (Emin, Emax, gamma) - minimum energy, characteristic energy, shape parameter.

Returns:

Fraction of bursts with E > Eth. Returns 1 for Eth < Emin.

Return type:

ndarray

Notes

Automatically initializes splines for new gamma values if needed.
