Kris: you are doing r=0.003 and r = 0; but what if you have small r, but non-zero? Why are we using r =0.003?
Some discussion about the level of delensing. Why are we using 60%? SH to contact Julien Caron.
Kris: What are you assuming about the spectral index for synchrotron? We should not assume a uniform spectral index. What beta per pixel? notes are not clear about the answer
Kris discusses his small scale synchrotron model: model is phenomenological, not physically motivated. It is tweaked to insert small scale 'mathematically', but not to violate what's know about the sky.
He takes Planck 353 GHz dust and modifies it. So the small scale synchrotron would be highly correlated with Planck's dust in small patches of the sky.
