This is equivalent to the RUN command, but produces a bias frame with preflash.

Format: FLASH <channel> <time> "

Channel: The name of the data-acquisition channel to be used.

Time: Dummy parameter.

Title: A title for the observation.

Examples: flash blue 0 "Check preflash level"

Queuable: Yes.

Comments: As soon as the CCD has cleared, the preflash LEDs are lit for the time previously set by preflash and the CCD is read out without opening the shutter. The observation type is recorded as FLASH. The time parameter is present to make the parameter list the same as for run; its value is not used.
