There is no point waiting for a response as generally the less thoughtful are distracted by trivia and nuisances willing to scribble graffiti on a working astronomical proposition.

Although this period is rather delicate although the conclusions are robust in line with imaging, there is no harm offering a glimpse for those interested in orbital dynamics. As the Sun is central and all stellar circumpolar motion is subtracted, the change in position of the stars from the fixed central point of the Sun will show variations in the speed by which those stars move from left to right of the Sun in response to the orbital motion of the Earth. Stellar circumpolar motion swamps this observation as proponents of RA/Dec don't take these things into consideration.

There is no point either in grumbling about priority when there is so much to do and besides, investigating astronomical imaging as a frontier is more exciting than trying to drag people kicking and screaming to that frontier.. Celebrate satellite imaging if it is all people can manage but the insight is here to stay.
