In response to a recent plea in a 3.5m night log:

>It would be very useful if there were a Java-based applet to display

>I'm thinking something similar to the experimental cloud camera

Such an application does already exist and is undergoing testing here
at UW.  A single X window displays the latest IR sky camera image, IR
satellite image, and guider image, along with plots of guider
performance (centroid relative to desired position, X & Y FWHM,
relative guide star intensity, exposure time, subfield position,
etc.).  It is not a Java applet as I found the cloud camera applet a
pain to write.  Rather, it uses IDL to paint a single, large (1000x600
pixel) X window.  At the moment, we have a dedicated screen in the APO
control room here at UW to display this information.

If someone at a remote site plans on using the guider extensively and
wants to try to have this window displayed remotely to an X screen in
your control room, contact me that afternoon, and I can try to set this
up, time permitting.  Should these experiments prove successful, it may
be possible for other sites to utilize this feature on a regular
basis.  However, for the moment, I'm just looking for a few volunteers
for evaluation purposes.
