Bases: Model

Parameters:

mpi_comm: object

MPI communicator object (optional, default=None).

nside: int

Resolution parameter at which this model is to be calculated.

max_nside: int

Keeps track of the the maximum Nside this model is available at by default 512 like PySM 2 models

smoothing_lmaxint

\(\ell_{max}\) for the smoothing step, by default \(2*N_{side}\)

Methods Summary

get_emission(freqs[, weights])	This function evaluates the component model at a either a single frequency, an array of frequencies, or over a bandpass.

Methods Documentation

get_emission(freqs: Unit('GHz'), weights=None)

This function evaluates the component model at a either a single frequency, an array of frequencies, or over a bandpass.

Parameters:

freqs: scalar or array astropy.units.Quantity

Frequency at which the model should be evaluated, in a frequency which can be converted to GHz using astropy.units. If an array of frequencies is provided, integrate using trapz with a equal weighting, i.e. simulate a top-hat bandpass.

weights: np.array, optional

Array of weights describing the frequency response of the instrument, i.e. the bandpass. Weights are normalized and applied in Jy/sr.

Returns:

outputastropy.units.Quantity

Simulated map at the given frequency or integrated over the given bandpass. The shape of the output is (3,npix) for polarized components, (1,npix) for temperature-only components. Output is in uK_RJ.
