Troubleshooting guide

Array Temperature Quick Look Plot Tool – This GUI will appear, along with an xterm messaging
window. Please do not close this window or the associated xterm to which messages are printed; you
can minimize the xterm or move it and the plot window to another space on the monitor. After about
30 minutes there will be ~3 points in the Record Temperatures log file, and you can hit the Update
button to plot the present temperature.

During the first execution of initflam.pl, you will be asked at multiple points whether you wish to
continue. In general, if the daemon windows say "listening on port", startup has been successful and you
should answer "y" (for yes). If you are re-running initflam.pl after rebooting MCE4 after a detector
controller crash (cf. § VII. Troubleshooting), but have left the daemons running (which is OK), the script
will complain that the Motor and MCE4 daemons are stalled, however these daemons are probably
functioning properly and you can type "y" to continue on.
NOTE: The MacMinis have four desktops (called spaces). If you move the mouse to the top right corner
of the right-hand monitor or the bottom left corner of the left-hand monitor, you will get a bird's eye view
of all of the four spaces and can pick one, or drag a window from one space to another. This a convenient
feature, which some might find annoying, and can be changed. One may also switch to another space by
clicking on the “spaces” icon in the dock at the bottom of the monitor screen.
NOTE: We recommend that one close, and immediately restart with initflam.pl, all three daemons
(Temperatures, Motor, and MCE4) once a day. You will also need to close the Record Temperatures
Window, and to quit out of the two temperature quick-look plotting utilities. We recommend that you do
this in the afternoon, possibly right before starting to take a set of pre-dinner dome flats or darks.
