Reshuffling of electronics in ISC-R3
Moved electronics to reflect new rack layout for ISC-R3 per D1001426-v10. This is to allow spacing for the new 2 omega auto-centering electronics. Work consisted of moving chassis a few U slots in the rack. All electronics remained on, and no cables were disconnected. Work will continue tomorrow to run field cables from CER to HAM6 racks. This will involve working over HAM6. Fil C. & Ed M. & Daniel S.
Around the same time, we noticed a shift in the dc offset of ASAIR 90 I&Q. Not surprising; we've seen this before when people work in or near the HAM6 rack. Jenne and I adjusted the digital ASAIR 90 I&Q offsets to compensate.
