(a)Upper-level energy. (b)Einstein A coefficient, where x(y) = x × 10y. (c)Statistical weight.(d)Critical density estimate, ncrit,T = Au/Cu, for T = 100 K. The collisional rate coefficients are taken from the references in column nine. (e)Survey designation: P = PRODIGE, A = ALPPS. (f)References for collisional rate coefficients. (*)Collisional rate coefficients are for the transition of the main isotopologues.
