TotalUnassociatedDiaObjectsMetricTask¶
TotalUnassociatedDiaObjectsMetricTask computes the number of DIAObjects that have only a single source (as the ap_association.totalUnassociatedDiaObjects metric).
It requires an alert production database as input, and is meaningful only at dataset-level granularity.
Processing summary¶
TotalUnassociatedDiaObjectsMetricTask queries the database (through Apdb) for the number of DIAObjects with exactly one source.

Butler datasets¶
Input datasets¶
dbInfo- The Butler dataset from which the database connection can be initialized.
The type must match the input required by the
dbLoadersubtask (default: the top-level science task’s config). If the input is a config, its name must be explicitly configured when runningTotalUnassociatedDiaObjectsMetricTaskor aMetricsControllerTaskthat contains it.
Retargetable subtasks¶
dbLoader¶
- Default
lsst.verify.tasks.apdbMetricTask.DirectApdbLoader- Field type
ConfigurableField
Task for loading a database from
dbInfo. Its run method must take one object of the dataset type indicated by dbInfo and return a Struct with an ‘apdb’ member.
