Tracking
|
When the telescope is tracking (and only during that), it propagates
some tracking related information through the dim-network. This page
shows the values of the latest received report.
The control deviation is the deviation measured between the shaft-encoder
position at the telescope axis and the command position by the controller.
Theoretically, real mispointing could be larger due to additional
bending of the structure.
If a dedicated source is tracked, a source name is displayed. If
the moon is above the horizon, the distance to the moon is displayed.
The colors represent
- No moon light is directly hitting the G-APDs
- The distance is very close to the direct or indirect field-of-view of the cones.
- The moon is within th efield-of-view. This condition should be avoided as much as possible.
Note that the color scales are not well motivated as of today. Anybody
is invited to investigate this issue in more details.

The graphics display the history of the control deviation. Note that it
is only updated during tracking and the time axis is just simply binned,
i.e. that one point represents one service update and they need
not to be equidistant in time.
