Size and orientation of 1-sigma uncertainty ellipse
Short axis : Size = 5.784599E-02 (arcsec); Direction =  -0.17344  0.98484
Long axis : Size = 6.254931E-02 (arcsec); Direction =   0.98484  0.17344
The confidence boundary shown below has been computed using the linear theory.

The line segment extending from the center to the edge of the plot represents the direction of apparent motion.

The raw data for this plot (same scale and axes) are given below:
