These errors are at the level of a few milliarcseconds.
65 milliarcseconds in size, with the long axis oriented north-south.
During the close alignment, the white dwarf's gravity bent the light from the distant star, making it appear offset by about 2 milliarcseconds from its actual position.
Most of these events will appear non-instantaneous, even taking up to a full second, due to Aldebaran's large angular diameter: 20 milliarcseconds, which is equivalent to 40 meters at the Moon's distance.
The observations and their longperiodic parts are depicted in Figures 1 and 2, in which the vertical scale is given in milliarcseconds (mas).
In close vicinity of zenith, planar approximation of image coordinates is reasonably accurate (error in zenith distance z < 5 milliarcseconds if z < 0.
Theory predicted frame-dragging should change the orientation of the craft's spinning spheres by only 39 milliarcseconds per year, about the width of a human hair seen from 400 meters.
The abscissa shows proper motion measured in milliarcseconds per year, while the ordinate plots proper motion time cosine (declination).
Dr Danny Steeghs, of the University of Warwick, said: "The incredible detail we can see on such small scales, about 100 milliarcseconds, which is the size of a one euro coin seen from about 40km, is only possible thanks to the adaptive optics technology available on large ground-based telescopes.
Omicron Ceti, the prototype Mira star, revealed itself to the Hubble Space Telescope as an irregular blob about 60 milliarcseconds wide.
This baseline at millimeter wavelengths enabled a resolution of 35 milliarcseconds, which is equivalent to a penny as seen from more than 110 kilometers away.
