Explanation
It is often useful to convolve an estimated CMB lensing map with a Gaussian beam before measuring correlation functions with galaxies and shears. If such smoothing is applied, we must account for it on the modeling side. This module accounts for such smoothing by multiplying the theoretical power spectra by the necessary beam factors.
##Parameters
These parameters can be set in the module's section in the ini parameter file.
If no default is specified then the parameter is required.
| Parameter | Description |
|---|---|
| shearkappa_section | section name where harmonic-space cross-spectrum between galaxy shear and CMB kappa is stored. Leave blank if none. |
| galkappa_section | section name where harmonic-space cross-spectrum between galaxy density and CMB kappa is stored. Leave blank if none. |
| beam_sigma_arcmin | sigma of Gaussian for smoothing CMB kappa (in arcminutes) |
| beam_fwhm_arcmin | FWHM of Gaussian for smoothing CMB kappa (in arcminutes) |
##Inputs
These parameters and data are inputs to the module, either supplied as parameters by the sampler or computed by some previous module. They are loaded from the data block.
| Section | Parameter | Description |
|---|---|---|
| shear_cmbkappa_cl | ell | integer 1d array, values at which c_ell is evaluated |
| bin_{i}_{j} | real 1d arrays for relevant i and j combinations. C_ell calculated at corresponding ell. | |
| galaxy_cmbkappa_cl | ell | integer 1d array, values at which c_ell is evaluated |
| bin_{i}_{j} | real 1d arrays for relevant i and j combinations. C_ell calculated at corresponding ell. |
##Outputs
These parameters and data are computed as outputs from the module
| Section | Parameter | Description |
|---|---|---|
| shear_cmbkappa_cl | ell | integer 1d array, values at which c_ell is evaluated |
| bin_{i}_{j} | real 1d arrays for relevant i and j combinations. C_ell calculated at corresponding ell after smoothing. | |
| galaxy_cmbkappa_cl | ell | integer 1d array, values at which c_ell is evaluated |
| bin_{i}_{j} | real 1d arrays for relevant i and j combinations. C_ell calculated at corresponding ell after smoothing. |
