Caption: Figure 1.

Parallax fitting results without incorporating geodetic blocks. The top panels present the eastward (left) and northward (right) positional offsets as a function of time. Similar to the top panels, the bottom panels show the eastward and northward offsets with the fitted proper motion removed. Outliers are marked by orange scatters.
