In anticipation of going to Observe last night (which didn't happen due to a lockloss sometime just before 1am), I had accepted some ISI SDF diffs while JimW was still here to approve them. I'm sure he'll look at his data more, and make a final decision on whether we should keep the sensor correction changes or not, but for now the Guardian will probably put the EY ISI back in its old nominal state, so we'll see a bunch of SDF diffs when we get to NomLowNoise.  Anyhow, I attach a screenshot of what I accepted, and we can re-accept the old values later today, until Team SEI decides to change the Guardian.
