NumberNewDiaObjectsMetricTask¶
NumberNewDiaObjectsMetricTask computes the number of DIAObjects created when processing data through source association (as the ap_association.numNewDiaObjects metric).
It requires task metadata as input, and can operate at image-level or coarser granularity.
Processing summary¶
NumberNewDiaObjectsMetricTask reads AssociationTask statistics from task metadata associated with one or more processed images.
It uses these statistics to count the number of new DIAObjects added when processing those images.

Butler datasets¶
Input datasets¶
metadata- The metadata of the top-level command-line task (e.g.,
ProcessCcdTask,ApPipeTask) being instrumented. Because the metadata produced by each top-level task is a different Butler dataset type, this dataset must be explicitly configured when runningNumberNewDiaObjectsMetricTaskor aMetricsControllerTaskthat contains it.
Retargetable subtasks¶
No subtasks.
Configuration fields¶
connections¶
- Data type
lsst.pipe.base.config.Connections- Field type
ConfigField
Configurations describing the connections of the PipelineTask to datatypes
metadataDimensions¶
Override for the dimensions of the ‘metadata’ input, when instrumenting Tasks that don’t produce one metadata object per visit.
