WP12746 h1omc0 Low Noise ADC Autocal Test

EJ, Jonathan, Dave:

For a first test we restarted h1iopomc0 three times to run an autocal on the low-noise ADC -- each time the autocal Failed. Next test will be to power cycle existing card leading to possible replacement.

WP12755 TW1 Raw Minute Trend Offload

Dave:

h1daqtw1 was configured to write it raw minutes into a new local directory to isolate the last 6 months of data from the running system. The NDS service on h1daqnds1 was restarted to serve these data from this location while the file transfer progresses.
