Examples of micro-irregularities in the rotational behaviour of the Vela pulsar and the events selected by the searches. Top: frequency residuals relative to a cubic model. Middle: two plots in the centre show the sizes Δν (top) and (bottom) of the GCs and AGCs (with filled and open circles, respectively, at the end of the bars) and of the other detected irregularities. Bottom: frequency derivative residuals relative to a linear model. The ν and datasets were obtained from fits to TOAs in a moving window 8 d long that moves by 1 d at each stride. The length of the horizontal line in the top panel is 8 d long.
