There are currently two ways of running NSFCam from HP. The first is to control the instrument remotely from the HP machines (kelvin or helmholtz). This is the preferred method. The second involves remotely logging in to the summit computer (stefan) and controlling NSFCam from that machine.


To control NSFCam remotely from the HP machines,

  1. Log in to kelvin or helmholtz with the observer's guest account.
  2. camxui &
  3. vf &
  4. On the Command Line, set the TCSHOSTNAME to be machine (where machine is either kelvin or helmholtz). (This will prevent the telescope from moving, should the observer set the mode to Nod (AB) while operating at HP.)
  5. On the Command Line, set the XUIHOSTNAME to be machine.
  6. Proceed with normal NSFCam operations.

To control NSFCam directly from the summit computer, while operating on the HP machines:

  1. Log in to kelvin or helmholtz with the observer's guest account.
  2. On kelvin or helmholtz, xhost + stefan
  3. rlogin -l account stefan (where account is the user account, such as guest01).
  4. On stefan, setenv DISPLAY machine:0.0 (where machine is kelvin or helmholtz).
  5. camxui &
  6. vf &
  7. On the Command Line, set the TCSHOSTNAME to be machine. (This will prevent the telescope from moving, should the observer set the mode to Nod (AB) while operating at HP.)
  8. Proceed with normal NSFCam operations.
Since the observer is now running NSFCam directly from stefan, there is now no need to set the XUIHOSTNAME parameter.
