InterpolatingComponent

class pysm.InterpolatingComponent(path, input_units, nside, interpolation_kind='linear', has_polarization=True, map_dist=None, verbose=False)

Bases: pysm.Model

PySM component interpolating between precomputed maps

Parameters

pathstr

Path should contain maps named as the frequency in GHz e.g. 20.fits or 20.5.fits or 00100.fits

input_unitsstr

Any unit available in PySM (see pysm.convert_units e.g. Jysr, MJsr, uK_RJ, K_CMB).

nsideint

HEALPix NSIDE of the output maps

interpolation_kindstring

Currently only linear is implemented

has_polarizationbool

whether or not to simulate also polarization maps

map_distpysm.MapDistribution

Required for partial sky or MPI, see the PySM docs

verbosebool

Control amount of output

Methods Summary

get_emission(self, freqs[, weights])	This function evaluates the component model at a either a single frequency, an array of frequencies, or over a bandpass.
get_filenames(self, path)
read_map_by_frequency(self, freq)
read_map_file(self, freq, filename)

Methods Documentation

get_emission(self, freqs:Unit("GHz"), weights=None) -> Unit("uK_RJ")

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

Parameters

freqs: float

Frequency at which the model should be evaluated, assumed to be given in GHz.

Returns

ndarray

Set of maps at the given frequency or frequencies. This will have shape (nfreq, 3, npix).
