After some hiatus we come back to the project with the hopes of lensing the CIB map "properly", by deflecting the sources and then getting the lensed CIB maps from these.

The relation connecting convergence and gravitational potential is

[math]\displaystyle{ \phi_{\ell m} = \frac{2\kappa_{\ell m}}{\ell(\ell+1)} }[/math]

Jason says that the kappa maps are in 

/scratch/r/rbond/jasonlee/cib_lensing2020/kappa_maps/total/

and his code is 

/scratch/r/rbond/jasonlee/cib_lensing2020/gal_catalog/mapmaker/project_galaxies_by_redshift_0545.py
