Using the tracker chip for standalone observations.
These are the instructions for the use of the tracker chip in standalone mode. It was designed for the observations of Charon occulting a star on 11th July 2005.
These instructions assume that you are observing with WFI and want to switch to the tracker chips standalone mode which will permit you to save a window of the guide camera at a fast rate (e.g. 0.5s).
- BEFORE YOU START: At w2p2ins, in wfi account: wfinsStopCCDs. This will ensure that the regular processes are down.
- rlogin wwffcd -l fcdrun
- su - vltmgr.
- Set the DISPLAY variable e.g. export DISPLAY=lxt12p2.ls.eso.org and test that the DISPLAY was set correctly by starting an xterm.
- export INS_ROOT=/net/w2p2ins/data/INSROOT/WFI This will set the INS_ROOT variable.
- export CCDNAME=wfovThis ensures the proper value of CCDNAME environment variable, which for the next step to work properly it has to be set to the mosaic (wfov).
- fstartfcd This will start fcdCon and a few other processes... wait, this may take a few seconds...
- From the recently opened fcdCon: first STARTUP and the ONLINE Be patient as these steps can take some time.
- Now we switch to the tracker chip: export CCDNAME=wfovt
- fcdSlcuCon& This starts a fcdCon for the tracker chip.
- Check that it says wfovt
- STARTUP (wait)
- ONLINE (wait)
- startRTD (wait)
- Chose mode0 (wipe) or mode1 (no wipe)
- set Save to file
- set "transfer one of _ " option to 1, so all images are stored.
- set "repetition" to the desired value
- AFTER YOU ARE FINISHED:
- Shutdown fcdCon wfov
- Shutdown fcdCon wfovt
- Exit wwffcd xterm
- Exit RTD
- At w2p2ins wfinsStartCCDs
The images will be stored in $INS_ROOT/SYSTEM/DETDATA They will have the name given in the wfovt fcdCon panel.
