Comparison between the Fermi-LAT data (in blue) with their Bayesian blocks (in black) and the total flux density of MOJAVE data at 15 GHz (in red). The dashed blue lines represent the time of ejections for different knots, found in the VLBA-BU-BLAZAR visibilities, and the blue lines are the corresponding errors, while the orange dashed lines represent the epochs when the knots encounter the standing shock “A1” with the corresponding errors. In green, the epoch in which “B12” was found.
