Main functions#
|
The function to convert C_ell to D_ell (i.e. ell*(ell+1)*C_ell/(2*pi)). |
|
The function to convert D_ell to C_ell (i.e. C_ell = D_ell*(2*pi)/(ell*(ell+1))). |
|
This function estimates the bias on the tensor-to-scalar ratio due to pointing systematics This function based on the paper: https://academic.oup.com/ptep/article/2023/4/042F01/6835420, P88, Sec. |
|
This function generates the CMB map used in the map base simulation of litebird_sim. |
|
Generate the maps with the lock file |
This function generates color scheme which is often used Planck paper. |
|
|
This function generates DataFrame which is used for FGBuster as instrument from IMo. |
|
This function loads the fiducial CMB power spectrum used in the map base simulation of litebird_sim. |

Methods#
Get the complex conjugate of the field |
|
|
Get the covariance matrix of the detector in mdim`x`mdim matrix form |
|
Generate observed noise map with the noise PDF. |
|
Generate probability density function (PDF) of the noise. |
|
Get the cross-link of the detector for a given spin number |
Initialize the scan fields data |
|
|
Get the output map by solving the linear equation Ax=b This operation gives us an equivalent result of the simple binning map-making aproach. |
Transform Top detector cross-link to Bottom detector cross-link It assume top and bottom detector make a orthogonal pair. |
|
Get the absolute pointing field of the detector |
|
Build the information to solve the linear system of map-making This method has to be called befure map_make() method. |
