Figure 7: A typical region of sky over a range of frequencies covered by CMB experiments. Synchrotron dominates at 1 GHz, free-free, synchrotron and CMB at 10 GHz, CMB at 100 GHz and dust at 1000 GHz. Flux is in $ΔT$ equivalent temperature in $μK$ . No atmospheric emission has been added. The CMB model shown here is for a standard cold dark matter model with $h = 0.5$ and $Ωb = 0.05$ .
