Table 4.
Results of the correlation study between radio GPs and γ-rays that appear to be correlated with radio GPs (resulting from the intersection values between linear fits of γ-ray MC simulations and data points in the right hand figures of Figs. 6 and 7).

Notes. The first column indicates the used data sample without phase cuts (marked “ALL”), only P1 and P2 in the VHE γ-ray data + MCs (marked with a γ) and P1, P2 based on Gaussian fits in the radio data (marked with an “r”). Their indices reflect whether the phase cuts are based on the radio, or γ-ray data. The acronym SW is standing for search window length, PCrab is the rotation period of the Crab pulsar, κbest is the intersection value, CI95% is the upper value of the corresponding 95% confidence interval, perr the probability to obtain the observed number of events based on the mean and standard deviation of the MC simulations and FUL the upper limit of the flux normalized to the pulsed VHE flux of the Crab pulsar.
