PowerLawFlux1D

class synphot.models.PowerLawFlux1D(amplitude, x_0, alpha, **kwargs)

Bases: astropy.modeling.powerlaws.PowerLaw1D

One dimensional power law model with proper flux handling.

For multiple n_models, this model only accepts parameters of the same unit; e.g., amplitude=[1, 2] or amplitude=Quantity([1, 2], 'photlam').

Also see PowerLaw1D.

Parameters:

amplitude : number or Quantity

Model amplitude at the reference point. If not Quantity, assume the unit of PHOTLAM.

x_0 : number or Quantity

Reference point. If not Quantity, assume the unit of Angstrom.

alpha : float

Power law index.
