Observing Specialists: G.Saurage
AzVeloScale: 579.5, 577.8; 578.7 (no change)
At checkout TSPEC dark was fine, then after mounting the instrument a test file was
all zeros (PR 929 again). Had to toggle arrayPower. After switching instruments, and
taking TSPEC off, a follow up flat was still fine. So, not every mounting and
dismounting causes the arrayPower to get lost.
The setup on Venus with TSPEC was a little tricky, but with Russet logged in to help
they got it worked out. Should be smoother subsequent nights.
The 3.5m enclosure dust counters were not reporting again.
