 Open all CHARA servers and GUIs as usual. The VEGA team will open their servers and software from the VEGA computer. \\  \\ If VEGA is running with CLIMB, then LDCs will need to be used. Bring up the LDC GUIs using the menu on zoot (under ESP Controllers). It's a good idea to home the LDCs at the start of the night. To home the LDCs, turn on the power button for the relevant telescope (the button will turn from red to green). Set the velocity to a non-zero number like 50 and click the [VEL] button. Then click the [HOME] button. You will see the position of the LDC go to 0.0. If the position gets stuck at "<>", then simply cycle the power on the LDC, set the velocity to 50, and home again. After homing the LDCs, turn the power off until you are slewed to the first target and have the reference cart set. If you turn the power on before then, you run the risk of the LDCs going to a bad position (< -10 mm or > 40 mm) and losing their position. If this happens, you will need to home the LDCs again. After you have the reference cart set, type "useldc on" and "autoldc on" into the ople server. Then turn on the power for the LDCs and click the [Ref] button on Cosmic Debris. The position of the LDC glass in mm should roughly match the postion of the carts in meters. (Follow direction under PAVO section if you need to home the LDCs during the night). \\  \\ If VEGA and CLIMB are both recording data simultaneously, then type "sds 4000" into the CLIMB server to increase the length of the data sequence on CLIMB. This will prevent CLIMB from going into a shutter sequence while it needs to be tracking fringes for VEGA. When the VEGA sequence finishes, click [STOP] on the CLIMB GUI to stop taking data and begin taking shutters on CLIMB. \\  \\ To co-phase CLIMB and VEGA, you will have to bring up the "Beam Combiner 1" GUI from the ESP Controller menu. Detailed instructions for co-phasing CLIMB and VEGA are available on the VEGA website. Please remind the VEGA observers to zero out any offsets added to the BC1 GUI before the end of run or before turning off the BC1 power. \\  \\ __Advice on running 3T CLIMB for use with 4T Vega:__ \\ VEGA is using beams 1-4, and have the telescopes setup in such a way so that the shortest and easiest baseline is 3-4 for them to track themselves. But to have the glass and the cart in the right place in relation to the reference cart, you have to have all 4 telescopes active which causes conflict in the Cosmic Debris because for having climb active, it says "no point in doing this with anything but three active scopes" So a work around for this is the following: \\  \\ 1. Lock the star with all 4 scopes via the sequence \\ 2. On the config tab on CD, uncheck the telescope on B4, hit send (the telescope will still be tracking on tiptilt and the cart will be close to where it needs to be for later. \\ 3. Align climb for beams 1-3 \\ 4. Scan for fringes on all 3 beams (first time to get offsets) \\ 5. Record 3 beams button, get all 3 fringes in the window. \\ 6. Now that the windows are up, on the ople gui, or on cosmic debris (I do ople) on the configure tab, recheck the telescope on B4, and hit send. The telescope will now be active for VEGA to track the 3-4 fringes after the man button is pressed. This will also keep the telescope activated for the next slew. \\  \\ {{https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif?direct&|external image cleardot.gif}} Open all CHARA servers and GUIs as usual.
