Explanation
It is often useful to apply a maximum or minimum ell cut to a CMB lensing map before measuring correlation functions with galaxies and shears. If such an ell-cut is applied, we must account for it on the modeling side. This module applies the lmin/lmax cut to the relevant cross-power spectra.
##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. |
| Lmin | minimum ell to impose for CMB kappa cross-spectra. |
| Lmax | maximum ell to impose for CMB kappa cross-spectra. |
##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. |
