The three cosmological models (Omega_0=1, Omega_Lambda=0), (Omega_0=0.3, Omega_Lambda=0.7), (Omega_0=0.3, Omega_Lambda=0) are considered, which extends our previous application (Lasenby et al. 1999 -\"http://xxx.soton.ac.uk/abs/astro-ph/9810123\"-, Dabrowski et al. 1999 -\"http://xxx.soton.ac.uk/abs/astro-ph/9810149\"-).
