Parallax and proper motion fits of G012.68−0.18, yielding a parallax of (0.416 ± 0.028) mas. The positions of the reference maser spot at 59.3 (triangles) km s^-1 were measured relative to the background quasars J1808−1822 (blue) and J1825−1718 (red). Left panel: position on the sky with a label for the first and last epoch. Middle panel: east (continuous line) and North (dashed line) position offsets with parallax and proper motion fits versus time. Right panel: right ascension (continuous line) and Declination (dashed line) parallax fits with the best-fit proper motions removed, showing only the parallax signature.
