onepower.add.UpsampledSpectra

class onepower.add.UpsampledSpectra(*args, **kwargs)

This class generates one or two Spectra, extrapolates them to the desired output grid and adds them if requested.

Parameters:

• z (array_like) – Output redshifts to which to interpolate and optionally extrapolate power spectra.

• k (array_like) – Output k-vector to which to interpolate and optionally extrapolate power spectra.

• fraction_z (array_like) – Redshifts of the red/blue fraction of galaxies in sample.

• fraciton (array_like) – Red/blue fraction of galaxies in sample as a function of redshift.

• model_1_params (dict) – Parameters for the first halo model.

• model_2_params (dict) – Parameters for the second halo model.

• extrapolate_option (str or float) – Extrapolation option to pass to interp1d.

• model (object) – Instance of Spectra(), pre-initialised for saving computing resources.
