If a night (or portion of a night) is fast read mode, we need to take the normal set of daily calibrations as normal (in normal read mode) to maintain our knowledge of the instrument. In addition to the normal calibrations we need to switch in to fast read mode and take a set of calibrations. This is probably best done after regular scheduled cals are finished (usually around 5:30pm HST) and before sunset. This can be a very narrow time window at some times of year.
After Automated Cals Finish
To change modes use kpfSetReadModeFast or kpfSetReadModeNormal as appropriate.
Then run the cals using kpfRunCalOB -f /kroot/rel/default/data/obs/kpf/FastReadoutCals.yaml
After Fast Read Mode Observations are Done
To change modes use kpfSetReadModeNormal as appropriate.
This must be done before the normally scheduled cals begin at 7am HST.
