Using the tracker chip for standalone observations.

Instructions

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.
