hi Immanuel, Chris,

B2/Keck analysis will also be the first time that beam systematics
deprojection is used in its full glory (we only used relgain
deprojection in the B1 analysis).

Going along with Chin Lin's email, I'm sure that we have been up front
in previous talks about far field A/B offsets. So if we told people
about them back when they were pretty bad, we should *definitely* tell
people about them now that we have both analysis mitigation and
improved hardware!
