Start guider eavesdropping

Guider eavesdropping allows you to monitor the image from the guide camera in real time. To start eavesdropping:

1. Log into manele (single-headed display next to hanauma) if you have not already done so.
2. Select the Guider Eavesdropping > Start eavesdrop option from the OpenWindows menu.

Start FACSUM

The ``Facilities Summary'' or FACSUM window is a real-time display of the telescope status. To run FACSUM:

1. On manele, Select the K2 telescope status menu > FACSUM option from the OpenWindows menu.
2. Resize the window as desired.

Start Xmet

Xmet is a meteorological display showing current summit temperature/dewpoint data. To run it:

1. Select the K2 telescope status menu > XMET - Weather option from the OpenWindows menu.
2. Adjust the size of this window as desired.

Enable DCS Rotator Control

The telescope drive and control system must be given explicit permission to run the instrument rotator. To do so:

• Click the Rotation button at the right side of the Dashboard to launch the rotator panel.
• If the status of the rotator is not UNLOCKED, then click on the UNLOCK button to make it so.
• Click the Allow DCS Control button at the lower left of the rotator panel, and release on the yes option to enable DCS control.
• Ask the OA to perform a "Standby/Init" of the rotator.
• Verify that the mode switches to DCS.

Open the DEIMOS hatch

Command the hatch open from the Dashboard GUI to allow the guider to see the sky.

Wait for dome to open

The Observing Assistant (OA) is not permitted to open the dome until after sunset. Please be patient while the shutter opens and the OA checks the initial telescope pointing.

Disable xbox practice mode

In IRAF, edit the parameters for xbox and set the value of practice to no.

Set the rotator angle

The DCS will not be able to locate targets until DEIMOS is explicity sent to a rotator position. Ask the OA to send DEIMOS to any position; for example, the position angle to be used for your first target.

Slew to vicinity of first target

When ready to move the telescope, the OA will ask you for your first target and load the coordinates from your starlist file. He or she will select a bright star near your target and will attempt to acquire that in the guider, then will double-check the accuracy of pointing by acquiring one or two additional stars from the SAO or GSC catalogs.

Focus telescope

Ask the OA to focus the telescope using the appropriate method:

• Autofoc on the guider if you will be using the longslit.
• Mira (replacement for MALIGN) if you will be doing imaging or multislit work.

Ensure that the DEIMOS position angle is set to the value you wil be using for your target, and to focus in the vicinity of your object.
