IMPORTANT: This file is now at the Wiki at pavo.wikispaces.com/susi-observing This file describes how to set up and run SUSI. This can be done from SUSI itself or from the ROCS room in Sydney or indeed from anywhere! Before observing check the weather at Narrabri. See the BOM or ATCA weather station (bookmarked on Firefox). If you are at Narrabri check: Is there anything physically in the way of the starlight or the delay cart (tools/telescope/bridge)? Are all the lights out? This file is /import/www/sifa/susi/Observing/procedures.txt Edit it as necessary ------------SET UP------------ Select your siderostats - a north-south pair from: N4,N3,N1,S1,S2,S3,S4 Note: N1 has no electronics at present - Nov 2009 Log-in to rocs Open an NX connection to peleas Do this with the red NX icon on the TL (top-left) display. Open a window to arthur if you are not using taskmaster Open the servers and GTK clients: This needs to be done in the following particular order to ensure all the connections work. Also open their respective GTK client if available - those with a star* From the SERVER window open SKYMON (not essential because it is generally running in the background) To see the sky image do 7, 6 (TV off/TV on) in the SKYMON server. Check the state of the sky over SUSI. From peleas (ie via NX) open Metrol Webcam - Check metrology signal is good Open VIDMONGTK N and VIDMONGTK S Visually check that the sids you intend to use are clear to go: Open VIDMONGTK N and VIDMONGTK S In VIDMONGTK N do 'TV ON' and 'CAM ON'. Select N#_CAM and visually check the heaters and bins are out of the way of the siderostats. Do the same for South. From the SERVER window open ACQLABJACK* OPTTAB2 OPCON: -Type 'run' into server window -Type 'sb' into server window -Check that Laser Current (South) is 'OK' and Freq is 'stable' Otherwise metrology laser may need resetting. -Make sure the cart is centered ("ZSet" sensor is "On"). - If it is not there, you want to bring it manually at the center and then type in "zfine" when "Zset" turns on. - Afterwards, type in "cen" so that the "OPD" is set to zero (not -146 or some other large non-zero number!!!). SIDCONs*: As they can be turned off after each use (unlike OPCON and LDC), their AV68Ks have to be set up. Run the 'Automatic Setup Procedure' Go through all the commands with "spacebar" and exit the "rtpcom" tests with "ESC". LDC: Check that crown wedge is realistic, status is ok PAVO*: If not using Taskmaster you have to tell PAVO which siderostats you are using. To do so, type in "nsid n#" and "ssid s#" replacing "#" by the number you're actually using. Finally in ACQLABJACK: type in 'pvopen' to open its connection with PAVO Make sure the AV68Ks (SIDCON N, SIDCON S and OPCON) are on "run" All the servers should now be ready and communicating with each other. You can now open all the gtkclient to ease the process. Open: -K108GTK -ROOFS -N# (N3 for now) Put in a periscope ('south in' or 'north in') -S# (S1 for now) ditto -PAVOGTK -ACQLABJACKGTK -TASKMASTER 1a. Make sure the alignment laser is off Open a web browser on peleas. Type ippower1 into address box (also ipower I/O Control is bookmarked). Switch laser off (Power1). Power2 is the picomotor control. Power3 is the green laser Click 'Apply' 2. Open the rooves Make sure with the help of SKYMON that the sky is clear and that no clouds can be seen. Make sure to keep an eye on the weather in SKYMON; clouds aren't good but rain definitely is something to avoid! Now with the help of VIDMON and ROOF GTK, open the rooves of the siderostats you're using. 3. In Taskmaster do: (Check these notes still apply, they are old scheduler notes - APJ) Taskmaster should make and set a new data directory (msd) on opening Do dir /export/snert/data/yymmdd (if necessary) if this fails type msd in an arthur window sid n? s? ? to set the sids an direction, eg. sid n4 s3 s reopen to make all connections pin to put the periscopes in fs 300 600 15 eg. to set fringe search parameters 3a. If Taskmaster is not working... Enter a star in ASTROMOD In a terminal (on Arthur), run ASTROMOD ie. 'astromod -kd xxxx n# s# ? where xxxx = HR# of target # = north or south siderostat in use ? = n or s for the periscope you are using (To log on Arthur, in a terminal type in "ssh -X observer@arthur" followed by the password). 4.PAVO Using PAVOGTK, open the display ("DISPLAY" button) and the waterfall diagram ("PLOT" button). In Display: Order is S-N-Combined You then have to set the gain for the pavo camera. For bright stars, a gain of 150 is good, for faint stars, it could go up to ~170. Click on GO/STOP to start the camera and take a background measurement for some time (~a minute is way enough). Enter the bg levels into pavo server: sal x y nal x y whrere x=bg level (see pavo), y = x +~500 (for a star) 5. PLC Tell OPCON to start tracking the star, either by going in the submenu "4 Tracking menu" then clicking on "1" or by typing the command "start_tracking" (the opposite being "stop_tracking"). 6. SIDCON Start tracking the star (click "Track"). Make sure no other periscopes are in the vacuum pipe and blocking the light. This can be seen by looking if any other green lights are on on the control room panel (these can be seen from the Metrol camera if not in Narrabri - start this on NX to peleas). 7.PAVO Make sure the background acquisition is turned off. 8. ACQLABJACK With the client, turn the camera ON and move the pellicle (to north, then south). Once the siderostats are tracking the star you should normally see the star (make sure the intensifier is on "2/3"). Then click "Track ON" and if everything is aligned and working properly the star light should make it to PAVO. On the PAVO server, look for the North and South servo indicator to turn ON. You can then proceed to the south beam or park the pellicle. 9. LDC Do the same with LDC by typing "track" (stop by typing "stop"). 10.PAVO To be completed, things aren't normally that simple... Now that the two (south & north) images can be seen in the left and middle target in the display, you can do a fringe search with the "Start" and "Rate" entries on the PAVOGTK. Typical value are -200 for the starting offset and 10 for the rate. If all goes right, you should get some fringes and PAVO should take (all of this should be automatic) a dataset and initiate the shutter sequence afterwards. If you haven't been able to get a dataset, cry and go read the 50 pages PAVO manual. Once you're done with that star, repeat the process (stop both the SIDCONs and OPCON from tracking before) at step 3 or close everything up. ------------CLOSING UP------------ When observing is over, the servers can technically be closed in any order, but first make sure that: The Siderostats are parked (click on "STOW" on both clients). The rooves are closed. Ensure the siderostat mirors are pointing down (to stow) before moving rooves. To make sure they're closed, see if the "N/S#_CL" sensor on K108 displays "OFF". The cameras (PAVO and ACQLABJACK) are shutted and parked. OPCON & LDC aren't tracking a star anymore. The PLC cart in back to its "ZSet" position. All the AV68K are on "SBY" (sids + opcon), this can be checkout on the ACQLABJACK server. In an arthur terminal, type speak skymon troff tron Now complete the end of night logs: endnight Fill in the SUSI Observation Report (from Firefox bookmarks)
