So it is a footprint then and I might show some of those maps and ask what do these footprints show in the early universe as to say, that given the inflationary timeline what can be garnered about looking back so far as to suggest 13.8 billion years and have such an imprint hold relevance, and equal the very nature of space-time itself.
The nature of the question for me is a "sensor mode developmental model" that chooses to exemplify gravitational waves over another and I had to make this clear for myself. So you can see where this has lead me. To where I want to further understand. If you choose not to show a comment then I guess that is where I lose.
Weber developed an experiment using a large suspended bar of aluminum, with a high resonant Q at a frequency of about 1 kH; the oscillation of the bar after it had been excited could be measured by a series of piezoelectric crystals mounted on it. The output of the system was put on a chart recorder like those used to record earthquakes. Weber studied the excursions of the pen to look for the occasional tone of a gravitational wave passing through the bar...

The analogy rests with how the nature of gravitational waves had been sounded so as to show a connection to the WMAP as a footprint. So you have this 2 dimensional map surface as to exemplary how gravitational waves may appear on it, yet, the visual extent of that correlation is representative to me of a defined configuration space. You need your physics in order to establish any correlation to the timeline of the inflationary model and to see that such a map reveals efforts to penetrate the Planck era. To suggest quantum gravity.

So indeed to have such a map is very telling to me not just of the imprint but also of the sensory mode we had chosen to illustrate that map of the B mode representation as a valid model description of that early universe.
