<P>Dear all:</P>
<P>In lambda.f90 of QE-5.0.1, I find a explanatory note "1 THz=50 K", <BR>which is used to evaluate the superconducting transition temperature Tc.<BR>But using E=hv=kBT, we can get 1 THz=47.99 K, so my question is the<BR>output of lambda.x is the actual Tc, or should be multiplied by 47.99/50?</P>
<P>Thank you for your help.</P>
