plancklens.sims.planck2018_sims¶
Planck 2018 release simulation libraries.
Note
These simulations are located on NERSC systems.
Note
Units of the maps stored at NERSC are \(K\) but this module returns maps in \(\mu K\)

class
plancklens.sims.planck2018_sims.
cmb_len_ffp10
[source]¶ FFP10 input sim libraries, lensed alms.
The lensing deflections contain the L=1 aberration term (constant across all maps) due to our motion w.r.t. the CMB frame.
-

get_sim_blm
(idx)[source]¶ Parameters: idx – simulation index Returns: lensed B-polarization simulation healpy alm array

cmb_unl_ffp10
[source]¶ FFP10 input sim libraries, unlensed alms.
-
static
get_sim_blm
(idx)[source]¶ Parameters: idx – simulation index Returns: unlensed B-polarization simulation healpy alm array

ffp10cmb_widnoise
(transf, nlevt, nlevp, pix_libphas, nside=2048)[source]¶ Simulation library with freq-0 FFP10 lensed CMB together with idealized, homogeneous noise.
Parameters: - transf – transfer function (beam and pixel window)
- nlevt – temperature noise level in \(\mu K\)-arcmin.
- nlevp – polarization noise level in \(\mu K\)-arcmin.
- pix_libphas – random phases simulation library (see plancklens.sims.phas.py) of the noise maps.

smica_dx12
[source]¶ SMICA 2018 release simulation and data library at NERSC in uK.
Note
This now converts all maps to double precision (healpy 1.15 changed read_map default type behavior, breaking in a way that is not very clear as yet the behavior of the conjugate gradient inversion chain)

class
plancklens.sims.planck2018_sims.
smica_dx12_SZdeproj
[source]¶ tSZ-deprojected SMICA 2018 release simulation and data library at NERSC in uK
Note
This now converts all maps to double precision (healpy 1.15 changed read_map default type behavior, breaking in a way that is not very clear as yet the behavior of the conjugate gradient inversion chain)
