6. You are now ready to initialize FLAMINGOS! This is done by running the command
♫ initflam.pl ♫
This script initializes agents and displays the following windows:
Temperature Daemon - This daemon reads temperatures from three different sensors in FLAMINGOS
with the following output written to the screen:
UFLakeShore208Agent::ancillary
>new reading:(2002:170:05:24:06.920436) 1,75.67 6,82.73 7,83.21
You should always keep an eye on the array temperature ( ~76 K, in the example above where it says
1, 75.67 ) and the MOS dewar temperature (~83 K, where it says 6, 82.73 in the example above) or
MOS worksurface temperature (7, 83.21). The array temperature should never vary by more than
~0.5 K. The MOS dewar temperature must remain below 200 K for successful imaging, although J
and H band imaging can be done even with the MOS dewar at room temperature. In normal operation
the temperature varies between ~78 K and ~95 K in a sawtooth pattern, depending on the time since
the last cryogen fill and the attitude of the instrument; if you are doing MOS observations, please do
not let it warm up above 95 K, as the Decker and MOS wheel mechanisms may bind up. Please
contact Dick Joyce, Ron Probst or Nick Raines if the MOS dewar deviates from this behavior.
Record Temps window - This window logs both temperatures every 10 minutes. It is sometimes easier to
monitor the array and MOS dewar temperatures from here. Please do not close this window or the
associated xterm to which messages are printed; you can minimize the xterm messaging window.
Motor Daemon - This daemon controls the motors which move all of the wheels. If the motor daemon
does not initialize, answer "n" (for no) to the initflam.pl query about continuing, quit the motor daemon
window and run initflam.pl again.
MCE4 Daemon - This daemon runs the MCE4 array controller. The first time this daemon is run, if
initflam.pl says it is not ready, look at the MCE4 daemon. If it is printing a string of messages about
uninitialized semaphores, quit initflam.pl, quit the MCE4 daemon window, and type ufstop.pl -clean at
the 4mguest@flmn-4m-1a prompt. Type CTRL-C after ufstop.pl has printed several lines of text and
has paused without returning the cursor. Then run initflam.pl once more.
UFSTATUS GUI - This window displays the temperatures, the bias voltage on the array, and the positions
of all of the wheels. Please do not close this window or the associated xterm to which messages are
printed; you can minimize the xterm. Note that it is NOT updated automatically; you must click the
update button in the middle of the GUI for the most recent values and positions. DO NOT press the
update button while any of the wheels are moving.
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 mayall-2 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.
MOS 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 mayall-2 monitor. After
