== Autoguiding ==
Ultimately the autoguider control will be integrated into the TCS, but for now it has a standalone GUIrun on 1ms1 via the Lesedi-NUC. To start Connect to the NUC via remote desktop, e.g. for Linux use the Remmina client, set the server to lesedi-nuc.suth.saao.ac.za and enter the username and password from the Lesedi User Resources document. Once connected to Lesedi-NUC, if the autoguider GUI isn't already running (or is not responding), open a terminal, login to 1ms1 and check for any autoguider sofwarejobs already running:
ssh -Y observer@1ms1.suth.saao.ac.za
ps aux | grep readPLC
The result might be:
root 1310 99.8 0.1 39384 13016 ? R Jun21 5284:08 python readPLCandLesediV1.py
root 14103 0.0 0.1 39384 13040 pts/11 S+ 14:41 0:00 python readPLCandLesediV1.py
root 20411 99.9 0.1 39384 13092 ? R Jun23 1187:37 python readPLCandLesediV1.py
observer 25808 0.0 0.0 14224 1032 pts/12 S+ 17:49 0:00 grep --color=auto readPLC
These processes remain "hanging" if the xyslides software was not exited properly from the EXIT button. You need to kill them using their IDs, e.g.:
sudo kill -9 1310 14103 20411
Then in the same terminal, check that the Lodestar cameras are connected:
observer@sa1:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 079: ID 1278:0507 Starlight Xpress Lodestar autoguider
Bus 001 Device 081: ID 1278:0507 Starlight Xpress Lodestar autoguider
If you do not see the Starlight Xpress listed then the cameras are not detected on the USB ports and the icron devices probably need power cycling.
Once the rogue processes are killed and the cameras are connected, start the autoguider GUI:
cd /home/observer/xyslide_lodestar_GUI_V5
sudo ./main_prog -depth 24
Points To run the finder chart software, open a new terminal (or a new window in the same terminal with CTRL-SHIFT-T) and login again to note1ms1:* The XY slides can move 20000 steps in X and 15000 in ssh -Yobserver@1ms1.suth.saao.ac.za* cd /home/observer/GS_FC python genfinderLesediFeb2020.py This brings up a finder chart and a coordinates box. To guide while start guiding: On the main autoguider GUI, if using SHOC, select Slide 0; or Slide 1 for Sibonise.If the status of any of the error codes (Err, XLL, XUL, YLL or YUL) is 1, click RESET, then INITIALISE.* To start continuous exposures with the autoguider Lodestar camera, enter a number (~2 seconds) in the box on the right, and click CONTINUOUS. ********* * If Enter the status of any target coordinates in the pink box and check that a finder chart of your field loads.Guide stars are to be selected from outside the error codes green box in the finder chart image. (Err, XLL, XUL, YLL or YUL) When North is 1Up in the SHOC/Sibonise image, click RESET, then INITIALISE.* It is not yet possible to select a guide star from a cataloguethe lower half of the image, so for now it's a bit of a fishing expedition.* Put values in both with X <20000 and Y boxes and click GOTO to move the slides<15000. '''As Y approaches 10000 it begins to vignette the SHOC field, so try to choose a guide star at low Y.''' ********** For a '''sky angle''' On the XY Slide Control section of 0the main GUI, iclick "Goto GS".eThis will send the XY slides to the position you clicked on the finder chart software. North up If it doesn't, both read the N-S coordinates of the guide star off the image and Eenter them manually; when the position is reached click "Pick guide star" and click on your chosen star in the guide camera image.Click the red GUIDE button -W buttons it should be turn green. For a sky angle of 180, they should both be clicked and turn redto indicate that it is guiding.* FAKE should always be red green "Fake is OFF" while guiding, as - this is a test functionfor engineering purposes.
