See more details at https://so-pysm-models.readthedocs.io/en/latest/so_pysm_models/models.html
Parameters: - target_nside : int
HEALPix NSIDE of the output maps
- has_polarization : bool
whether or not to simulate also polarization maps Default: True
- pixel_indices : ndarray of ints
Outputa partial maps given HEALPix pixel indices in RING ordering
- TT_amplitude : float
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.
- Toffset : float
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_amplitude : float
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
- rTE : float
TE correlation factor defined as: rTE = clTE/sqrt(clTT*clEE) Default: 0.35 from Planck IX 2018
- EtoB : float
ratio between E and B-mode amplitude. Default: 0.5 from Krachmalnicoff et al. 2018
- alpha : spectral tilt of the synchrotron power spectrum (D_ell).
Default: -1.0 from Krachmalnicoff et al. 2018
- beta : synchrotron spectral index.
Default: -3.1 from Planck 2018 IX
- curv : synchrotron curvature index.
Default: 0.
- nu_0 : synchrotron reference frequency in GHz.
Default: 23
- seed : int
seed for random realization of map Default: None
