it is not. it is an old formula for a matter-dominated universe as I remember. forget it. some people still use it (peacock). dig some ads or astro-ph stuff.
- sonic speed in the relativistic plasma is c/sqrt{3}. right? ;-) BUT:
c_s is NOT constant at that time. it is not that easy and I would rather start with learning what people have already done than playing hide-and-seek with numbers.
THESE QUESTIONS ARE ALREADY ANSWERED ;-) - and answers were applied to soft such as CMBfast which you use often ;-)
In other words, "dig some ads or astro-ph or CMBfast code". ;)
Certainly learning what other people have already done is a good idea - but being skeptical about it is also useful and helps in understanding.
E.g.: http://arxiv.org/abs/astro-ph/0310186 Cosmological parameters and the WMAP data Authors: Antony Lewis
which supports the claim that the WMAP data is not as easy to interpret as is claimed by the official team...
