We report on a measurement of the angular spectrum of the anisotropy of the microwave sky at 30 and 40 GHz between l = 50 and l = 200. The data, covering roughly 600 deg2, support a rise in the angular spectrum to a maximum with δTl ≈ 85 μK at l = 200. We also give a 2 σ upper limit of δTl < 122 μK at l = 432 at 144 GHz. These results come from the first campaign of the Mobile Anisotropy Telescope on Cerro Toco, Chile. To assist in assessing the site, we present plots of the fluctuations in…

TLDR
Using a Bayesian analysis to constrain the amplitude of the perturbation spectrum, it is shown that adiabatic hot-dark-matter models are convincingly ruled out and cold- dark- Matter models have anisotropies near the derived limits.
