The first image shows a yao session running inside xemacs (bottom left), complete with all graphical outputs (here you can see the image, the WFS, the DM surface, the Strehl history), and the ytk GUI to modify variables in real time.

The image below shows the graphic display window that you can choose to have when running
aoloop()
. These graphics are useful to debug systems or see at one glance what is wrong. I do recommend to use it (and it's fun) for the first runs, when you are dimensioning the system. During batch/long runs, disable it to gain speed.
The upper left area shows instantaneous images at the positions requested in the parfile (here every 10" horizontally and along the first diagonal). The images are enlarged locally are centered on their correct position along the X & Y axis. The position of the guide stars are shown by a red cross (here, there is only one).
The upper right area shows wavefront sensor spots (or curvature sensor extra-focal images) for all guide stars, again at their correct geometrical locations.
On the bottom left, you find the instantaneous shapes of all deformable mirror, and on the right, the instantaneous (black) and time averaged (red) Strehl ratio.

Similar graphic window for a MCAO system (mcaolgs.par
)

An example of a graphical configuration screen. These specify the position of the actuators (numbers, colored=valid, black=extrapolated), WFS GS beams intersection with the DM altitude plan (solid lines) and outside envelope of all rays coming from all science objects (dotted line).

In addition to the above graphical display, and independently selectable, is the "control screen", that displays the state of many system variables in alphanumeric. Here you can see a progress bar, the state of all the WFSs (measured tip-tilt error, uptip and uptilt -for an LGS- sent to the uplink steering mirror) and centroid gains, the TT mirror integrated commands (arbitrary units for now, I'll fix that soon) and the Strehl ratio at all the request wavelengths (average, rms, min and max refer to spatial -field of view- characteristics).
