Can transmission spectrum exceed 1 within bias window?

Hello siesta users,

I’m trying to simulate a ZnO nanoribbon structure in siesta. When I performed the transport calculations, for a few bias points within the bias window, the transmission spectrum value exceeded 1. The transmission spectrum gives the probability of transmission of electrons. Since it is a probability function its value shouldn’t exceed 1. Are my simulation results correct? Can someone help me where I could be possibly making mistakes if they are wrong? How can I solve this issue?

Thank you.
