Hello,<br>
<br>
I'm trying to understand what exactly estimated SCF accuracy is. Does <br>
anyone know where I can find a formal definition of what it is and how <br>
it is being calculated? The structure of the output file implies that it <br>
is related to the Harris-Foulkes and the total energy, but it is clearly <br>
not the trivial difference between these two quantities.<br>
<br>
Thanks in advance,<br>
