Total proper emitting area of the equatorial thin disk between rin = max[rth, rISCO] and rout = 30M as a function of the wormhole deformation parameter λ (spin a* = 0.998). The solid curve shows the relativistic proper area computed from the disk surface metric, while the dashed curve shows the corresponding Euclidean reference area π(rout2 − rin2) using the same rin.
