Discovery Papers

Smoot et al. 1992 paper (post script) announcing discovery
- Figure 1 post script file (550Kb) currently not in place
  - A. Maps and overlay for comparison with {\it COBE} DMR maps: %Top is COBE DIRBE (Hauser \etal) 240-micron wavelength dust map. Top is IRAS 100-micron wavelength zodi-removed dust map. Middle is Galactic coordinate grid and source positions. Bottom is the Haslam et al. 408 MHz sky survey.
  - B. COBE DMR (A+B)/2 maps at 31, 53, and 90 GHz The maps have been smoothed with a 7-degree FWHM Gaussian, which when combined with the approximately 7-degree FWHM Gaussian beam shape results in about a 10-degree smoothing on the sky.
  - C. COBE DMR (A-B)/2 maps at 31, 53, and 90 GHz. The maps are processed identically as B). The sky signal is canceled by the subtraction but the average instrument noise remains the same.
- Figure 2 post script file (50Kb) figure of the 53 GHz correlation function as a function of Galactic latitude cut angle.
- Figure 3 post script file (100Kb) figure of the 53 x 90 GHz cross correlation function and monte carlo simulation of expected signal for scale invariant primordial spectrum.
