Parameters

nsideint

HEALPix NSIDE of the output maps

has_polarizationbool

whether or not to simulate also polarization maps Default: True

pixel_indicesndarray of ints

Outputa partial maps given HEALPix pixel indices in RING ordering

TT_amplitudefloat

amplitude of synchrotron TT power spectrum (D_ell) at at the reference frequency and ell=80, in muK^2 and thermodinamic units. Default: 20 from the amplitude of PySM-s0 synchrotron model at 23GHz in the region covered by SO-SAT.

Toffsetfloat

offset to be applied to the temperature map in muK. Default: 72 from the mean value of the T PySM-s0 synch map at 23GHz in the region covered by SO-SAT

EE_amplitudefloat

same as TT_amplitude but for EE power spectrum. Default: 4.3 from the amplitude of S-PASS E-modes power spectrum at 2.3GHz in the region covered by SO-SAT, rescaled at 23GHz with a powerlaw with beta_s = -3.1

rTEfloat

TE correlation factor defined as: rTE = clTE/sqrt(clTT*clEE) Default: 0.35 from Planck IX 2018

EtoBfloat

ratio between E and B-mode amplitude. Default: 0.5 from Krachmalnicoff et al. 2018

alphaspectral tilt of the synchrotron power spectrum (D_ell).

Default: -1.0 from Krachmalnicoff et al. 2018

betasynchrotron spectral index.

Default: -3.1 from Planck 2018 IX

curvsynchrotron curvature index.

Default: 0.

nu_0synchrotron reference frequency in GHz.

Default: 23

seedint

seed for random realization of map Default: None
