MergeDetectionsTask¶

Python API summary¶

from lsst.pipe.tasks.mergeDetections import MergeDetectionsTask

classMergeDetectionsTask(schema=None, initInputs=None, **kwargs): Merge sources detected in coadds of exposures obtained with different filters...

attributeconfig: Access configuration fields and retargetable subtasks.

methodrun(catalogs, skyInfo, idFactory, skySeed): Merge multiple catalogs...

Retargetable subtasks¶

skyObjects¶

Default: lsst.meas.algorithms.skyObjects.SkyObjectsTask
Field type: ConfigurableField

Generate sky objects

Configuration fields¶

coaddName¶

Default: 'deep'
Field type: str Field

Name of coadd

connections¶

Data type: lsst.pipe.base.config.MergeDetectionsConfigConnections
Field type: ConfigField

Configurations describing the connections of the PipelineTask to datatypes

cullPeaks¶

Data type: lsst.pipe.tasks.multiBandUtils.CullPeaksConfig
Field type: ConfigField

Configuration for how to cull peaks.

idGenerator¶

Data type: lsst.meas.base._id_generator.SkyMapIdGeneratorConfig
Field type: ConfigField

Configuration for how to generate catalog IDs from data IDs.

maxSamePeak¶

Default: 0.3
Field type: float Field

When adding new catalogs to the merge, all peaks less than this distance (in arcsec) to an existing peak will be flagged as detected in that catalog.

minNewPeak¶

Default: 1
Field type: float Field

Minimum distance from closest peak to create a new one (in arcsec).

priorityList¶

Default: []
Field type: str ListField

Priority-ordered list of filter bands for the merge.

saveLogOutput¶

Default: True
Field type: bool Field

Flag to enable/disable saving of log output for a task, enabled by default.

skyFilterName¶

Default: 'sky'
Field type: str Field

Name of `filter’ used to label sky objects (e.g. flag merge_peak_sky is set) (N.b. should be in MergeMeasurementsConfig.pseudoFilterList)
