edges_analysis.sky_models.SkyModel.at_freq

SkyModel.at_freq(freq: float | ndarray, index_model: IndexModel = ConstantIndex(index=2.5)) → ndarray[source]

Generate the sky model at a new set of frequencies.

Parameters:

  • freq – The frequencies at which to evaluate the model (can be a single float or an array of floats).

  • index_model – A spectral index model to shift to the new frequencies.

Returns:

temperature – The sky maps as numpy arrays at the new frequencies, shape (Nsky, Nfreq).
