Power Spectrum circa 2000

Key Concepts

The power spectrum circa 2000 looks like:

The power spectrum exhibits a cleanly detected peak at a multipole l~200 and tentative evidence for the expected features at higher multipoles.

Now let's step back and try to understand the origin of these features.
