Below are the steps for acquiring internal arcs and flats.

1. Run the configAOforLamps command in a NIRC2 waikoko xterm. This will configure the AO bench for acquiring spectroscopic flats and arcs.
2. Using the lamp command, toggle lamps on and off

   • For example, to toggle the argon lamp on and off, use the following commands:

     • lamp argon on
     • lamp argon off
   • For the internal flat lamp, the lamp name is "white", for a white light source (type "help lamp" for details).
   • Running the lamp command without an argument will provide the status of the lamps:

          waikoko{nirc5}1: lamp
                           argonpwr = 0  
                           kryptpwr = 0  
                            neonpwr = 0  
                           xenonpwr = 0  
                            lamppwr = 0  
     

     The flat lamp = "lamppwr" in the lamp command output above.
3. Setup NIRC2 for acquiring flats or arcs. See the exposure recommendations below.
