Constraints on radio source clustering towards galaxy clusters:
  application for cm-wavelength simulations of blind sky surveys
  We constrain radio source clustering towards $Planck$-selected galaxy
clusters using the NVSS point source catalogue. The constraint can be utilised
for generating realistic Sunyaev-Zeldovich effect (SZE) mocks, and for
predicting detectable clusters count and quantifying source confusion in radio
surveys.
