2D region with the 1–﹩3\sigma ﹩ contours for the parameters α and Υ in the ﹩{{R}_{{\rm h}}}=ct﹩ universe, using a sample of 240 SLSNe Ic, simulated with ΛCDM as the background cosmology. The simulated model parameters were ﹩{{{\Omega }}_{{\rm m}}}=0.27﹩, ﹩{{{\Omega }}_{{\Lambda }}}=0.73﹩, and ﹩{{H}_{0}}=70﹩ km s⁻¹ Mpc⁻¹.
