We report on a measurement of the angular spectrum of the cosmic microwave background (CMB) between l ≈ 100 and l ≈ 400 made at 144 GHz from Cerro Toco in the Chilean altiplano. When the new data are combined with previous data at 30 and 40 GHz taken with the same instrument observing the same section of sky, we find (1) a rise in the angular spectrum to a maximum with δTl ≈ 85 μK at l ≈ 200 and a fall at l > 300, thereby localizing the peak near l ≈ 200, and (2) that the anisotropy at l ≈ 200…

TLDR
This work uses a covariance-matrix approach to estimate the precision with which cosmological parameters can be determined by a CMB temperature map as a function of the fraction of sky mapped, the level of pixel noise, and the angular resolution.
