Detector Status
Real-Time Analysis
The incoming data from all detectors is analysed in real-time before being written to the database.
This analysis consists of the calculation of coincidences between all possible detector pairs. Additionally each individual and total coincidence detection rate is determined.
In order to ensure the validity of the data at all times, each detectors reliability is judged.
Reliability
Determining factors include e.g. quality of GNSS signal, effective DOP or the steadieness of detection rate.
For a detailed view, you can check out the relevant code at our github.
Additionally to the standard requirements, individual events can cause an instant unreliability mark due to exceptionally bad time resolution or no valid GNSS fix. Those events are automatically rejected.
Compare the code to see the detailed requirements.
Possible detector status
Status | Data is processed | Description |
---|---|---|
offline | no | The detector is not connected or experiences network problems |
online | no | The detector is recently connected |
reliable | yes | The detector is connected and all parameters are deemed good |
unreliable | no | The detector is connected but experiences network problems or has sub-optimal runtime parameters |
Possible reasons
reason | Description |
---|---|
miscellaneous | No reason has been specified |
time_accuracy | The mean time accuracy of the detector was outside the specifications |
time_accuracy_extreme | The time accuracy of a single event reached an extreme value |
location_precision | The mean location precision of the detector was outside the specifications |
rate_unstable | The standard deviation of the event rate was too large compared to the mean |
missed_log_interval | The detector missed a log interval (One for unreliable, Three intervals for offline) |
