Hi . When you look at the CMb with low contrast it should look like a uniform colour. But when you turn up the contrast you see the differences in temperature at 1 part in 100,00. I seem to remember seeing a tool somewhere where there was a slider you could adjust and see this change in a visual representation. But having searched around the web I can't find it. Anyone know of such a tool or a video of such a tool? Im looking for something like this: http://www.chromoscope.net But this slider lets you look at the sky in different wavelengths. I want something that will let you look at the CMB with different level of contrast. Any ideas?
