FYI -
per ongoing work in SEI, I've started committing the changes for the BSC-ISI improved sensor correction to userapps.
It is OK to svn up your userapps. Don't be alarmed if you'll see a bunch of new screens, c-code, and models and some new library parts models in the ISI part of the userapps.

I'm updating the various instructions now on how to install all this stuff. (T1800414)
An SVN up should not have any impact on what is running at the sites,
but,
the overview screen for the BSC-ISI now contains 2 links to the sensor correction, the original one, which should still work in exactly the same way,
and
a new one, which is mostly non-functional until you replace the isi2stagemaster.mdl in the various models with the new isi2stagemaster_SC_2018.mdl library part.
Detailed instruction on making real changes are in progress.
