I need to know the magnitude of the velocity perturbations (peculiar velocities) dv at time of last scattering as function of the multipole moment.(adsbygoogle = window.adsbygoogle || []).push({});

The temperature power spectrum of CMB shows temperature fluctuations dT/T ~ 10^-5. That naively suggests the peculiar velocities were dv/c ~ 10^-5. I need more precise estimate than that since the Dopler effect is a small contribution to the dT/T in CMB.

Any reference where dv are derived and shown numerically for different multipole moments?

I need numbers like dv/c = 10^-5 or 10^-4 etc.
