get_emission
(self, freqs: Unit("GHz"), weights=None) > Unit("uK_RJ")[source] [edit on github]¶ 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 tophat 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:  output : astropy.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 temperatureonly components. Output is in
uK_RJ
.
