All Implemented Interfaces:

Serializable, PickConnected

public class NoThArLight
extends ErrorEvent
implements PickConnected

An error event sent by the adapter if the calibration unit is not available and it needs human interference. This error should spark e-mailing of someone responsible at the home institute as this error cannot be fixed from people on site. There is no corresponding calibration-yes error because per definition this error need human intervention and restart of the system.
This error has the pipe flag raised to allow broadcast of the calibration availability to the scheduler. Targets that do not rely deadly on calibrations may still be executed.

This error is never produced as an explicit new NoThArLight, but rather produced as a broadcast in the (looping) sequencer. It shows up in the master log (as it is issued by the sequencer), but has its roots in the adapter. This makes an image, grabs its fits-moments box an funnels both to a moments trigger. This moments trigger (calibhalo.trigg) has a line

 momentslist=4000,-1.;20000000,400000000
 

where it states a minimum amount of ADUs to reach in the box (4000) in the example above and also a desired contrast (via the variance of the ADU counts, here between 2E6 and 40E6.
