Dear Basir,

<div class="">your 2nd root is not converging (not even close).  I would warrant to guess there is another state very close by or your active space is not sufficient to</div>
<div class="">describe this state.  I’ve copied this to the whole list since others have more experience with this part of the program.</div>
