We consider the adjoint restriction inequality associated to the hypersurface {(τ, ξ): τ=±| ξ| 2, ξ∈ R d} at the Stein-Tomas exponent. Extremizers exist in all dimensions and extremizing sequences are precompact modulo symmetries conditional on a certain inequality, which we verify in the case d∈{1, 2}.
