Vela’s glitch on February 1st. 2019 as measured at IAR in the 1400 MHz band. Ephemeris for the pre-glitch epoch were taken from Sarkissian et al. (2017) and the glitch date from Kerr (2019). The errorbars at one σ level are taken directly from the output of PRESTO and are likely to represent an underestimation. The dispersion is larger for short observations (10–15 min) than for long ones (> 60 min). We highlight that at MJD 58487 the data points from A1 and A2 overlap and are hardly distinguishable.
