Bases: KPFScript
Estimate the duration of the input OB. Uses estimates of instrument
configuration time, slew time, acquire time, and readout time and combines
those with the information in the observing block to estimate how long it
will take to execute the observing block.
ARGS:
:fast: bool Estimate the duration assuming fast read mode?
:OB: dict or ObservingBlock A fully specified observing block (OB).
