When is selector called to select next target?
Selector (rts2-selector) is process responsible for selecting new observational targets. It sends targets IDs using next command. You can imitate selector behaviour by running rts2-mon, selecting EXEC component and typing: next 1000 to select target with id 1000. The selection is executed on the following occasions:
When observatory is switched to ON state, so the executor knows what to observe
during last exposure on last exposing camera in script, so the executor is keep updated what to observe as the next target
every idle_select seconds, so new targets are selected even if some long script is running. The value of idle_select defaults to 300 seconds (=5 minutes). It can be changed by providing –idle-select parameter to rts2-selector (most probably in etc/rts2/services file).
