Angular separation from the core versus time for Gaussian jet features of the MOJAVE data. Colored symbols indicate robust features for which kinematic fits were obtained. The 1σ positional errors on the individual points typically range from 10% of the FWHM restoring beam dimension for isolated compact features to 20%, represented as a black cross in the plot, of the FWHM for weak features (see e.g., Lister et al. 2009, 2019, 2021).
