class darkhistory.spec.transferfunction.TransFuncAtRedshift(spec_arr, eng=None, in_eng=None, rs=None, dlnz=-1, spec_type='dNdE', rebin_eng=None, with_interp_func=False)

Transfer function at a given redshift.

Collection of Spectrum objects, each at different injection energies.

Parameters:

List of Spectrum to be stored together.

eng : ndarray

The energy abscissa of each Spectrum.

in_eng : ndarray

The injection energy abscissa.

rs : ndarray

dlnz : float

d ln(1+z) associated with this transfer function.

spec_type : {‘N’, ‘dNdE’}, optional

The type of spectrum saved.

rs : float

Redshift of this transfer function.

rebin_eng : ndarray, optional

New abscissa to rebin all of the Spectrum objects into.

with_interp_func : bool

If true, also returns an interpolation function of the grid.

Attributes:

spec_arr : list of Spectrum

List of Spectrum to be stored together.

dlnz : float

d ln(1+z) associated with this transfer function.

rs : float

Redshift of this transfer function.

interp_func : function

The 2D interpolation function.

Methods

append(spec)	Appends a new Spectrum.
at_eng(new_eng[, interp_type, bounds_error, …])	Interpolates the transfer function at a new energy abscissa.
at_in_eng(new_eng[, interp_type, …])	Interpolates the transfer function at a new injection energy.
at_rs(new_rs[, interp_type, bounds_err, …])	Interpolates the transfer function at a new redshift.
at_val(new_in_eng, new_eng[, interp_type, …])	2D interpolation at specified abscissa.
integrate_each_spec([weight])	Sums over each individual spectrum with some weight.
plot(ax[, ind, step, indtype, fac])	Plots the contained Spectrum objects.
rebin(out_eng)	Re-bins all Spectrum objects according to a new abscissa.
redshift(rs_arr)	Redshifts the stored spectra.
sum_specs([weight])	Sums the spectrum in each energy bin, weighted by weight.
switch_spec_type([target])	Switches between the type of values to be stored.
totN([bound_type, bound_arr])	Returns the total number of particles in part of the spectra.
toteng([bound_type, bound_arr])	Returns the total energy of particles in part of the spectra.
