udas_camera_mimic command

This page is part of the ING manual INS-DAS-29 Operations manual for UltraDAS.


This command starts a mimic for one camera controlled by UltraDAS. The mimic appears in a window on the selected X-server.


   udas_camera_mimic [-display <d>] [-geometry <g>] <camera> &
where camera is the formal name of the camera (e.g. EEV13, WFC); case is significant in formal names. The display-name d is the name of the X-server on which to display the mimic (e.g. lpss13:0.1). The geometry string g is in the standard format for X11 windows (e.g. -0-0 to park the window at the bottom-right-hand corner of the display).


    udas_camera_mimic -display taurus:0.0 -geometry +0-0 WHTWFC

Notes and caveats:

This command is normally invoked from startobssys. Observers should not normally invoke udas_camera_mimic directly.

You may run any reasonable number of mimics from one camera. "Reasonable" is determined by cumulative load on the camera server-programme and on the DRAMA message net: two mimics are fine, three or four are possible. Ten mimics on one camera are silly and 20+ are likely to damage the system.

Udas_camera_mimic should be run on the system computer. It can run on the DAS computer (if told of a suitable X-server), but that usage wastes CPU cycles in the DAS that are better used for taking data.
