MergeMeasurementsTask¶

Python API summary¶

from lsst.pipe.tasks.mergeMeasurements import MergeMeasurementsTask

classMergeMeasurementsTask(schema=None, initInputs=None, **kwargs): Merge measurements from multiple bands...

attributeconfig: Access configuration fields and retargetable subtasks.

methodrun(catalogs): Merge measurement catalogs to create a single reference catalog for forced photometry...

Retargetable subtasks¶

No subtasks.

Configuration fields¶

coaddName¶

Default: 'deep'
Field type: str Field

Name of coadd

connections¶

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

Configurations describing the connections of the PipelineTask to datatypes

flags¶

Default: ['base_PixelFlags_flag_interpolatedCenter', 'base_PsfFlux_flag', 'ext_photometryKron_KronFlux_flag', 'modelfit_CModel_flag']
Field type: str ListField

Require that these flags, if available, are not set

minSN¶

Default: 10.0
Field type: float Field

If the S/N from the priority band is below this value (and the S/N is larger than minSNDiff compared to the priority band), use the band with the largest S/N as the reference band.

minSNDiff¶

Default: 3.0
Field type: float Field

If the difference in S/N between another band and the priority band is larger than this value (and the S/N in the priority band is less than minSN) use the band with the largest S/N as the reference band

priorityList¶

Default: []
Field type: str ListField

Priority-ordered list of filter bands for the merge.

pseudoFilterList¶

Default: ['sky']
Field type: str ListField

Names of filters which may have no associated detection (N.b. should include MergeDetectionsConfig.skyFilterName)

saveLogOutput¶

Default: True
Field type: bool Field

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

snName¶

Default: 'base_PsfFlux'
Field type: str Field

Name of flux measurement for calculating the S/N when choosing the reference band.
