ConfigureForCalibrations

Bases: KPFScript

Script which configures the instrument for calibration exposures.

  • Powers on requested calibration lamps
  • Configures FIU to calibration mode
Parameters:
  • OB (ObservingBlock) –

    A valid observing block (OB).

Functions Called:

  • kpf.ObservingBlocks.ObservingBlock
  • kpf.calbench.IsCalSourceEnabled
  • kpf.calbench.CalLampPower
  • kpf.fiu.ConfigureFIU
