 The very same methodology was then followed but with the redshift-distance relation now determined through the use of Ned Wright's cosmology calculator (implemented in the Python programming language). The input data was also switched from a random N-body simulation to a Gadget2 simulation where the canonocal unit cube was of length 250 Mpc/h. The beam was simulated out to redshift 0.6. This was initially due to the lack of a simulation of sufficient size such that it would result in a 4 degree beam at //z = 1//. Cosmological calculations were then done and the results showed that our maximum redshift would be 0.6 and thus a beam width at this redshift is 2.56 degrees (//Θ(z) = 1x(1+z)^2// degrees).  The very same methodology was then followed but with the redshift-distance relation now determined through the use of Ned Wright's cosmology calculator (implemented in the Python programming language).
