Enhancement of VHE photons around occurring radio GPs resulting out of data sets (marked with crosses) and VHE γ-ray MC simulations (indicated by bars). Upper plot: results for a perfectly uncorrelated VHE γ-ray signal in the MC simulations (κ = 0), while lower plot: flux enhancement results for an injected VHE γ-ray signal which is perfectly correlated with GPs resulting from the radio data in a centered search window (κ = 1). The latter plot shows more clearly an increase of the number of VHE γ-rays centered on radio GPs for shorter search windows resulting from the data sets, indicating that the correlation is located at κ <  1.
