Notes. Columns from left to right: (1) component ID, (2) estimation of the time in which it was ejected from the core, (3) time at which it crosses the quasi-stationary region, (4) proper motions, (5) apparent speed, and (6) projected distance to the core in pc. Q8 and Q21 are the quasi-stationary components identified between 2011–2013 and 2016–2020, respectively.
