ewokstomo.tasks.energycalculation.SpectrumStats

class ewokstomo.tasks.energycalculation.SpectrumStats(inputs=None, varinfo=None, node_id=None, node_attrs=None, execinfo=None, profile_directory=None)

Bases: Task

Stats on an attenuated spectrum.

Inputs

• energy_eV: array-like (eV)

• attenuated_flux : array-like (ph/s/0.1%bw)

Outputs

• mean_energy_eV: Flux-weighted mean using bin weights: weights = flux * ΔE / (0.001 * E).

• mean_idx (int): Index of energy_eV closest to mean_energy_eV (−1 if N/A).

• pic_energy_eV: energy at which flux * ΔE / (0.001 * E) is maximal (NaN if N/A).

• pic_idx (int): Index of that maximum (−1 if N/A).

Parameters:

• inputs (Optional[Mapping])

• varinfo (Optional[dict])

• node_id (Union[str, int, tuple, None])

• node_attrs (Optional[dict])

• execinfo (Optional[dict])

• profile_directory (Optional[dict])
