<p><span lang="EN-US">Mark,</span></p>
<p><span lang="EN-US"> If you have access to the TESS Storage
library I would highly recommend switching Type60 out for
Type534. Type60 can get into some numerically unstable regions
from which it doesn't recover. In v18 we dropped Type60 in favor
of a few other tank models specifically because of those
problems.</span></p>
