2D confidence contour in w₀ − w_a plane for our model using CMB+DESI+DES data combination. The dash-dotted line is a phantom line. Above this line, the allowed region is always non-phantom, whereas below it the allowed region is early phantom and late non-phantom. Dots represent different MCMC realisations. The colour-code shows the value of Ω_Λ that allows for consistency with the above cosmological probes.
