FYI -

We've updated the ISO_RAMP_OFF.c code, and the ISI model update should be ready to install again on site - with caution.

Previous attempt (see alog 41368 and comments there-to) was a complete fail. We can't figure out why. We updated the c-code anyway to eliminate the chance of divide/0 errors (good practice, at least) and are glad that Jonathan and Dave pointed this out. The new code is the same name and saved in userapps revision 17231, see SEI log 1338 for testing notes. If you want to be sure you have the correct version, look near the top of the file and you will see the line

* v2 - April 2018 - remove the div/0 issue and cleanup - BTL, Dane Stocks.

As discussed with Hugh - We can not duplicate the errors here on campus. We can not explain the errors. The c-code update seems like a good idea, but so far as we can tell, it shouldn't make any difference - so-

please do be careful and continue to make good notes so we can figure out what's up.
