lens_img

This is a flat-sky CMB lensing demo for teaching.

created by Bin HU and Zhengyi Wang @ BNU

  1. run lens_img2.py, which produces an unlensed primary CMB map according to the input spectrum.

  2. run lens_template.py, which produces a inverse square(or cubic) lensing potential map.

  3. run dif_matrix.py , which produce a matrix of computing 2d gradient.

  4. run mixing.py, which produces the lensed CMB map.

You can’t perform that action at this time.
