I have some questions about convergence. Taking FFTGvecs for example, we need do several tests on convergence and normalization to find a proper setting. When we do self-energy calculation, we can confirm convergence by checking QP gap with respect to FFTGvecs. My confusion is how can we confirm that the result is converged when we do response-calculation ? Is there any guideline for convergence testing ?

Another question is about normalization. Can we say that the output information below confirms wavefunctions are normalized ?

Thank you !
