Summary
----------------------------------------------------------------------
. Night lost to weather. Thunderstorms at sunset, then rain, high
humidity & cloud.
. Continuation of stray light tests with the autocollimator and track
tests.
. Could not get tracking with AC and needed to remove the
Mother-Of-All-Baffles in order to get closed loop control with the
throttled AC. Subsequent tracks all worked fine (tried all extreme
azimuths).
. Looks like the AC stray light has been beaten down to ~60 ADUs (~80e),
not quite the desired 50e, but maybe good enough? Ambient dome
straylight is at ~20 ADUs and there's clearly a few LEDs still (like
hexapods). Inside payload it looks like there only ~10 ADUs above dark.
. Cal Sys flat field pattern is still not centred on BCAM (x=422, y =
646). Might need to verify that the axis of illumination is
perpendicular to screen.
