lsst.ap.association¶
The ap_association package provides tools for associating DIAObjects to DIASources, persisting this association, and computing DIAObject summary statistics.
Contributing¶
lsst.ap.association is developed at https://github.com/lsst/ap_association.
You can find Jira issues for this module under the ap_association component.
Task reference¶
Tasks¶
- FractionUpdatedDiaObjectsMetricTask
- Task that computes the fraction of previously created DIAObjects that have a new association in this image, visit, etc..
- NumberNewDiaObjectsMetricTask
- Task that computes the number of DIASources that create new DIAObjects in an image, visit, etc..
- NumberUnassociatedDiaObjectsMetricTask
- Task that computes the number of previously-known DIAObjects that do not have detected DIASources in an image, visit, etc..
- TotalUnassociatedDiaObjectsMetricTask
- Task that computes the number of DIAObjects with only one associated DIASource.
