Details after 1985 of dX and dY residuals from LLR observations, using changing windows of 50 counts and within 70 days. (While it is stated that setting the number of normal points to 50, it appears that there may be 67 windows (out of 483, i.e., more than 10%) that contain fewer than 50 points, in which case the window length is about 70 days.)
