\caption{Generalised Kendall's test probabilities for the null
  hypothesis that no relation exists between any two given quantities.
  The sample includes the IFS objects and the RLQs in H91b. The values
  in brackets give the correlation coefficients. The observed
  properties involved here are: the total luminosity in \lya\ in the
  EELRs ($L_{{\rm Ly\alpha,neb}}$), the flux from the QSOs in the
  broad \lya\ line ($L_{{\rm Ly\alpha,QSO}}$), the maximum
  extension of the \lya\ nebulae (size), the quasar luminosities
  estimated at the rest-frame 912~{\AA}
  ($L_{{\rm Ly\alpha,912~{\AA}}}$).
