<P>Dear Colleagues</P>
<P>I am a new user of Molpro. </P>
<P>Here, I have a question about the results of Molpro calculations.</P>
<P>In the output files of CCSD(T) single point calculation, I saw the following three lines after CCSD part:</P>
<P> Norm of t1 vector: 0.14674325 S-energy: 0.00000008 T1 diagnostic: 0.01729386<BR> D1 diagnostic: 0.03928771<BR> Norm of t2 vector: 0.80498319 P-energy: -1.14561206</P>
<P>Could you please tell me the meaning of these items and the normal range of corresponding values.</P>
<P> </P>
