After a little thought, I actually understood what the graph is showing and I am amazed at the accuracy of the deviation measurements.
While I was trying to determine the meaning of the method used, I began to wonder if a more accurate method might be possible:
Since the orbit of the Earth is ~584M miles, and light travels ~186K MPS, it should be possible to make phase relationship measurements between actual point sources(target) from close points(objective) on our orbit, while moving across and perpindicular to the wave boundary, of the light from an interstellar object. Wouldn't these types of measurements give a more accurate interpretation? This is assuming the CCD Camera discrimination is fine enough for something more than a coarse measurement such as the range finder mechanism which measures the strength of a field view, rather than individual point objects.
Or am I totally off course on this?

I guess your method is based on that the phase of light from the star is observed differently on earth in different seasons, say, summer and winter. It's a nice idea, isn't it? Although most of light having visible light length coming from stars or nebulae is incoherent, if you select specific spectrum of polarized light among them, it might be possible to obtain accurate information of distance between the star or nebula and earth.
