The Control Task

The main window of the control task is shown in Figure . This window contains status displays for the five subsystems managed by the control task (Telescope, ADC, CCDs, Positioner and the AAOmega spectrograph). Any of these sections can be removed from the display by clicking the button in the top right hand corner. It can be restored to the display using the Display menu.

A number of options are controlled through the Commands menu which contains the following commands:

Initialise -- This command causes the control task to load and initialise all the subsystems.

Reset -- When the system is initialised the Initialise entry is replaced by the Reset entry. This brings up a dialogue which allows a number of different levels of system reset. The Recover option is the most useful. This can be used to make the control task reload any task on aatlxy that has crashed or been deleted. NOTE: don't reset while the positioner is running, or the CCD are exposing.

Task Status -- This brings up a window showing the status of all the subtasks managed by the control task.

Report -- This outputs information on the subtasks in the messages window.

Delete Tasks -- This can be used to delete one of the subtasks. It is most useful if a task gets hung for some reason. Delete the task and then use Reset/Recover to reload it.

Display Configuration -- This can be used to display information about a fibre configuration file.

Find Fibres on Spectrograph -- This option runs a sequence which records CCD frames with each fibre illuminated in turn, which can be used to determine the mapping of pivot numbers to fibre positions on the slit. This option is only used for maintenance purposes.

Set System Time -- Enough said
