The collimation command can also be
accessed from the GUI by selecting the Experiment tab
from the Setup
top-level tab. To change the collimation values, the green button
at the bottom of the tab must be changed from "Monitoring ...
Click to allow changes" to "Changing ... click
to monitor". Type in the
collimations in the collimation numerical controls
(preMONO=source-monochromator; M-S=monochromator-sample;
S-A=sample-analyzer; A-D=analyzer-detector) and commit
the changes by clicking on the blue Update Parameters
button.
