equation for angular diffusion scale (thetad)

Post by Tristan L Smith » July 06 2023

Hello,

I am having a hard time finding the equation used in CAMB to compute the angular Silk diffusion scale (which, in CosmoMC, has the symbol 'thetad').

Can someone point me to where it is computed?

Thank you!

Best,
Tristan
