Compilation of CMB Anisotropy Observations 1992-1999
Vertical error bars represent 1 sigma uncertainties and horizontal error bars show the range from l_min to l_max. The line thickness is inversely proportional to the variance of each measurement, emphasizing the tighter constraints. All three models are consistent with the upper limits at the far right, but the Open CDM model (dotted) is a poor fit to the data, which prefer models with an acoustic peak near l=200 with an amplitude close to that of \Lambda CDM (solid). .

WOMBAT Challenge simulation
This is a CMB anisotropy map that might be observed by the MAP satellite at 90 GHz, 13' resolution, containing CMB, instrument noise, and foreground contamination. The resolution is better than can be represented in a full-page postscript file. (From the WOMBAT site).

CMB + Large-Scale Structure for \Lambda CDM
Compilation of CMB anisotropy detections (boxes) and large-scale structure observations (points with error bars) compared to theoretical predictions of standard \Lambda CDM model. Height of boxes (and error bars) represents 1 sigma uncertainties and width of boxes shows the full width at half maximum of each instrument's window function. (For more figures like this, check out Extracting Primordial Density Fluctuations).
