You can do everything the COW does from the command line, but the COW puts all of these controls in one handy location so that you don't have to remember the command names.

Option Descriptions

Check Centering After Nods?

When executing a nod sequence on sky, the system can pause before starting an exposure and allow you to verify that the object is centered in the slit (by taking a SCAM image, for example, and adjusting the telescope position to center the target in the slit). Select from the folowing values:

• yes: Pause after each telescope nod in order to check centering. This is the default.
• no: Do not pause after nods, just begin the next integration. Teams observing in the thermal IR should select this, since they will not be able to see the targets on SCAM and are unlikely to perform any recentering.

The command-line equivalent is "wait4center on|off".

Check Configuration on GO?

When executing a script from the NIRSPEC Echelle Format Simulator (EFS), the system can verify that all movable stages are in the requested positions before starting an exposure. This adds about 10 seconds to the start of each exposure sequence. Select from the following options:

• yes: Verify that stages are in position when starting a script. This is the default.
• no: Skip the verification step. This may save you about 10 seconds per script if you use the same setup all night.

Command-line equivalent: "wait4config on|off".

Notification Sound on Finish

When an EFS script completes, the system will play a notification sound on hanuama's speaker. The default sound is "gong", but you can select from among several options.

Flatlamp Warmup Time (sec)

When an EFS Lamps Only script or a Calibration Acquisition Tool script is run, this parameter will wait the specified time for the flatlamp to warmup. The default is 15 seconds, the lamp should be fully warmed in 120 seconds.
