Pulsar glitch analysis for PSR J0007+7303. The weighted H-test is calculated according to Eq. (2) using photons within the 170-day time window sliding over the entire data set with 17-day steps. For each window scans over f and ḟ were performed. The maximum value of H to ḟ for a given f is color-coded (see color scale at top). The vertical axis shows the time midpoint of each time window. The horizontal axis shows the offset in f.
